under 12volts

[marauder410]

im having alot of trouble with my car after i accidently put the positiveonthe negative and negaive on psitive and the air suspension just droppeddd

i blew my radio fuse and i did this with the battey in my trunk when hooking it up to my audio system

now with just the battery under hood car WILLL not start i need the under hook battery AND thr audo battery in trunk for my car even to start

when both hooked up starts no problem but under 12volts

with everyting in trunk unhooked and just my BRAND NEW RED TOP OPTIMA battery hooked car will not start and not even turn radio on

i was so tired when doing this and i think i fried something electrical and now car has been messed up ever since

fired my air suspension, switching to springs bec cant figure it out, blew fuse behind my radio changed fuse and worked fine and now needs both batteyrs hooked up and still have under 12volts, like at 11.2

im so pissed i did this to my car and cant get it running right again

[marauder410]

any suggestions please i know its something electrical maybe like i fired the computer or something

[RubberCtyRauder]

do you have a volt meter? which battery got hooked up wrong under hood or trunk battery? Your alternator could be fried which means it wont charge and you've been running on the reserve battery power and now there is none left. Less than 12 volts is often an alternator issue. You needa volt meter to find out a few things. when the car is off and when it is running

[Roadwarrior]

My guess would be the battery isolator/under hood battery shorted out, positive battery cable to the starter and/or the alternator {internal short}not charging as it should due to the accidental cable connection of the trunk battery for the audio system.:dunno: I would start with checking the alternator output first.

[marauder410]

i have a 250amp db alt and swithced to my stock alt and still have volts

i did this to the kinetiks hd2000 in my trunk when connected wrong termianls

[marauder410]

switched alts and still low volts

[marauder410]

i did do a 2 guage wire big3 upgrade and it was some cheap 2 guage wire so maybe the wire itself is fried maybe but if so then why when i have both battteys hooked up it will start just low volts. when i have just my NEW red top optima battey under hook so jusice at all

[marauder410]

could maybe the cheap wire itself be fried to the alt, i have a fuse holder in between it

[GetMeMyStogie]

Perhaps you fried one of the batteries, and it has now become a huge current sink. Try running with one battery disconnected. Then, disconnect that battery and connect the other one and see if your voltage improves.
Despite being brand new, if the RED TOP OPTIMA is fried, it is no longer of any use. If it still looks super-clean, maybe you can get it exchanged.

[GetMeMyStogie]

The 'cheap wire' to the alternator actually consists of a type of fuse called a 'fusible link', which looks just like regular wire. It's very possible the fusible link has popped.

Replacing a fusible link with (or adding) some sort of high-amperage fuse in a fuse holder will probably introduce resistance between the alternator and battery, and the fuse will probably be less reliable over time. I wouldn't recommend it. There have been discussions on this board about what's better - have a look, or try googling on the subject.

[marauder410]

so your saying i use replace that wire

i planned of redoin the whole big 3 with stinger hpm exper 0-guage wire

right now i have the cheap 2-guage wire i think it was like 30 bucks for 20 feet so yea really cheap

i have a digital exp i think is the brand digital fuse holder in between the bat n alt with a 300 amp kicker fuse and a 250amp db electrial alternor

think is before i turn car over car OFF it say 12.70 volt onthe digital stinger terminals i have and soon as turn car over drops to 8 and nothing comes on car will nto start kicks over but will not start

n when i have both batteyrs connect red top in frong n kineitks hc 2000 in trunk will start and when i turn stuff on healights and ac batter lights comes on and bout 11 volts. when i have everything off the car drives but still low volts but seems fine into i tun a/c and headlights on n thats when the batteyr light comes on

[marauder410]

i took both batterys to the advanced auto and had them hooked up and they had they both are fine no bad cells just need charged

but all in all why would the darn air bags suspension just drop like that just bec i connected the worng terminals in trunk

just dont make sence to me thr air suspoension would go up because of this mistake they just dropped completly soon as i connected them

well tom we will see if everything goes as planned install my springs and hop it sits right and batterys getting charged install them and replace the big 3 wires wit 0-guage stinger wire and hop my MM is back to normal again

[GetMeMyStogie]

... hop my MM is back to normal again

Hope - my (least) favourite diagnostic tool.

[fastblackmerc]

Well Sparky....

Sounds like you fried the alternator. That is why the voltmeter reads 12 volts... alternator not charging....

When the batteries were checked I bet the underhood battery was below 12 volts, not enough to turn the starter motor.

The air compressor going out is just a coincidence.

[marauder410]

mo not a coicidnece soon as i did that with the terminals the whole rear end dropped the second no it wasent a coincidence at all i did that by touching terminals on wrong sides

[marauder410]

i had a stare alternaotr and put that one on and still doing the same thing as i stated above so no its not the alternator

[MrBluGruv]

This may be a large undertaking, but can you go back completely to stock before you modified this stuff and see if the problem persists then?

Changing your wire size will make -0- difference, you need some better diagnostic skills, as opposed to thinking a 300 amp fuse and a 250 alternator will make some type of difference. It's kinda like saying stickers add horsepower.

Start with a service manual for the car, and inverting polarity will kill electronics, even if it's done for just a short bit. Was the key on when you did that? Just so you know, the PCM controls the alternator on all panthers from 2003 and up, so I would "hope" it's just a fusible link that's killed and not all the supporting electronics in the car.

I will imagine I'll get some crazy response, but the truth is what it is. I would suggest the next car you buy not be something that is limited production, if you plan to "mod" it. Or at least find someone nearby with the ability that can help/do the work for you.

[Blackened300a]

Considering your car starts with your trunk batteries and not the battery under the hood makes me think you fried some relays/fuses hooking up the terminals the wrong way and your rear setup is bypassing whatever issue you are having up front. The link looks like a piece of wire and depending how blown out it is, you won't even notice its blown unless you use a voltmeter to check continuity to all of your components. You may wanna look for a professional to help figure out the problem before you start throwing money or performing tests that may result in more issues then you already have.

[JoeBoomz]

If you haven't already, I would check (or just replace) all of the relays and fuses in the box adjacent to the battery and under the driver side dash.

[marauder410]

i checked all the fuses and gonna replace the relays

[marauder410]

i acually know alot about cars it was a dumb mistake i happens

i swapped out alts and still having this problem

[Mac-MerC]

Just take it to the dealership, simple as that.

[justbob]

This may be a large undertaking, but can you go back completely to stock before you modified this stuff and see if the problem persists then?

This ^ is first step to take.

[marauder410]

i tryed everythingg i put stock alt on and unhooked my enitre auto system and even returned the tune back to stock and still nothing

when i have just the underhood battery hooked up and volts will not stay up i can even just press the lock on my keypad and just see the volts on my stinger terminal drop to like 9 volts. so as i press the buttom go to 9 volts then back up to 12.75 right after

im so confused im so pissed at myslef for making such a stupid mistake

[marauder410]

i guess to the dealership it is soon as iput them springs on tom since i did something to the air suspension at same time it just dropped some bs man

[justbob]

ALL of us make mistakes... Keep it in stock configuration untill you find something. Sounds like you have a constant dead short in the system. The battery tests fine, but yet anything used weakens it severely. Something has to be pulling power at all times to cause this, could be as simple as a sensor remaining energized, or mutiple for that matter.

[marauder410]

when i get my rear springs and get it drivign able im going to take it to a guy i know owns a taxi conmany and has nothing but crown vics and fixes them to and had the dealership scanners and will tell me whatever is wrong with my car

[marauder410]

i know its definatly something electrical juts hope nothing tooo major i canget the car started with the 2 batterys but under 12volts and when just the one under hook one no start

batteys tested good
swapped alternators
checked all fuses/ relays
unhooked everything in trunk
returned tune to stock

still nothing ive been soo bummed when my MM is down im down feels like i been sick ever since FORREAL this kills me i so OCD with my marauder its not even funny

messed up my whole air bag suspension,blew fuse behind my headunit, and now with only main battery car will not start and when both battyers hooked up starts no problem but still low volts

this is the worst thing ive ever done and i fix and work on my car ALLL the time. do most of the work myself

[Local Boy]

Hang in there Brutha....Happens to most of us, who dare to learn on our cars....Certainly did me...

My humble thoughts...

If you need two Batts to run...I would suspect Ground (-),...every time I made a bad electrical error...things would melt...including the wires...Everywhere!...I won't even start on how my watch shorted out my ride...Talk about the shock of my life, since I was wearing it!...Just part of the learning curve...:)

The question I would ask myself is...Why does it need two (2) Batts. to complete the electrical circuit (car Starts)...? Why isn't each Batt. able to complete the electrical circuit (No start)? The reason will be causing the low volts...

I would hook one up (Batt) and trace back to see if power reaches the starter, then see if it grounds (IMPORTANT: Move wires around while you are looking at the volt meter) ...Then do the other...I'll bet there will be a difference...and that is where you can focus your attention...If your'e lucky... you will see the volt meter go dead then come back as you move a specific wire...Bingo!

Look at your ground cable for melting...Look for cracks across the diameter...

Hope this helps...

Best of Luck...

Aloha

[marauder410]

thanks alot yea im going to install these Heavy duty sunoco springs tom to fix the rear end problem instead of spending 400 to fix the airbag suspension and ill never have to worry about that again so it will be drivable for a start...

then going to replace my whole big 3 upgrade wire with stinger 0-guage wire since i used a cheap 2-guage wire maybe one of the ground wires from my big 3 are loose and causing poblems

i narrowed it down to its somethign under the hook since when that battery alone is hooked up will kick overrr so not starter but will not start since low volts

i switched my alternators and still low volts and bought new under hood battery so thats not the problem

checked alll relays and fuses under hood and under steering wheel all OKK

im thinking its a loose ground wire from my big 3 upgrade or the cheap wire got fried and not holding a charge when kick over car

will do one more day of messing with it if cant figure it out then will drive it over to Bob bell ford in glen burnie who does all my work..

[sailsmen]

Buy red tape and mark the positive wire. I use different colors to identify different part locations. If you are color blind get a label maker.

[marauder410]

i used loom red for positive and black for ground of course

[marauder410]

im sending my car over to bob bell bec i cannot figure out why my voltage is low and causeing everything to act up.

just cant take it nomore need my car fixed and need a expert to look at it there just gonna hook it up to there computer and tell right there exacually what is wrong with it

i tryed many things cant figure it out so off to bob bell after i told you guys the dummiest mistake of my life i think touched the negative w pos/n pos wit neg and messed my car up big time

so bad darn temp guage is goin up n down my fan isnt coming on low voltage blew fuse behind headunit and juts seems to be running funny so its def something electrical just hope it not too serious but my luck it will be like the computer burnt up or something who knows

but will keep you posted just out of curiosity when people was tryna give me idea on what it could be and nothing worked so will keep you posted

gonna have it towed from my house to bob bell since my insure has the towing thing and never used it and i have 200 tow miles im paying for it so gotta use it one day so thats one plus and im really cool with the guy steven that works there and will work with me

[DOOM]

Let me know what the problem is.

[justbob]

Very curious as well. I thought we had it nailed a few times.. These things are just hard as hell to diagnose over the web. Good luck and hope its something minor. Remember, we ALL make stupid mistakes! IT HAPPENS. At least you came right out stating that and took the offered help.

Now do ME a favor and type better! :D Hard as **** to understand sometimes LOL

Once again, hope its minor and back to action quickly.

Sent from my Ally while ruling the world from my toilet.

[marauder410]

well car is now there and steve said he will call me about noon tom and tell me what the problem was

will keep you guys posted

yea i know my typing is bad sometimes justs type to fast and i think of it as long as they understand a misspelled word isnt such a big deal

[breeze]

I should have took mine there instead if another ford spot. Wasted my damn time basically and still no answer for my problem.

[ctrlraven]

Sometimes it sucks to admit defeat with a car but probably a good idea to take it to the dealer so nothing further happens to your MM.

[breeze]

Dealerships don't waste time if there not gonna make money off a car.

[marauder410]

right thats whyim going ot let the experts tell me whats wrong with it before i start replacing stuff that dosent need to be replaced

they will hokk it up to there computer and within a half a hour they will know exacually what the deal is

[ctrlraven]

Yeah they may say that but that is not always the case. Not every problem will show up on the computer.

[marauder410]

well of course not EVERY problem but most of them sure will

[Local Boy]

Hope all goes well...You did your best to find it...Electrical is the most difficult...

Aloha

[marauder410]

yea this is the first time ive been really slumped, usually guys will give me things to look for and check and i will get the part and fix it but with a electrical problem i juts cannot figure out whats going on :depress::shake:

[marauder410]

got the news today and said i would post wheni found out since we all were pretty slumped so when i touched wrongs terminals with each other

i knew it was a electrical just couldnt like when and they said something around a ground wire burnt in half and something around the strapss. cant remeber what excuallythey said but pretty much burnt up a eletrical ground wire and thats why was acting funny

so thats pretty good new to me and said that it will only cost 120.00 to fix it and everything will be back to normal crazy how one wire will make the car act so crazy like a mind of its own

[screamn]

Always need a good ground source for electricity to flow.

If this is amiss there will be all kinds of problems continuously or the dreded few occassions.

Happy to hear that the problem was located and soon will be fixed.

Guess you didn't get ripped by the "Stealership" aka Dealership.

BTW: have the "Stealership" save the ground cable that was fried/burnt to a crip so you can see the damage.

[marauder410]

good idea yea im gonna tell them to let me see the wire you replaced bec iknow how they do it could have been a bad ford full iso relay and cost 10 bucks and they say they replaced this and that

[marauder410]

hey its me again the person who has been having all kinds of problems since i did that accident installing my audio battery in trunk when i short circuited it and so so...

told you guys i would let you know what they told me about the air suspension dropped and caused all my electrical stuff to act up and car would only start with the both batteyrs hooked up under hood/ trunk battery with only under hood will not start.with both hooked up it will start no problem at all but low volts under 12v.

my thermostat would go up n down and a weird beeping noise and fans wasent working juts acting weird.

they said i had a burnt up ground wire that was burnd in hald and somethign about a sleeve they had to make instead of buying a new one so they did all that checked over eveything after replaicing the ground wire that was burnt up and he said everything was good now. everything was working and all was ok and said my total was 180.00 or something in that area.

since my car was already there i had the motor rebuild just over a year now and ive always had a little little pinging noise coming from the top intake or the driver cylinder somewhere, i thought it was normal since a mod motor or whatever but when went to a meet heard 3 other MM and there was nice n quite. so i was like ok thats not normal and next time at bob bell im going ot get them to look at it since they are the ones that installed the rebuild motor and they do all my work that i cannot do.

since day one driving the car aways just over a year now ive always heard that noise and put little over 10k in a year and went to ocean city twice and never had a problem from that little tinging noise and started to get a little louder i noticed. steve said my car was done and i told him ok thats whats up but can you check that noise for me since its already there and he said of course.

i got the motor rebuild from JASPER they do strictly motor and trans. i got my motor over a year and a got a transmission from them and got both dobne before i was a memeber here i wish i knew a littel more like i do now be i would of most definatly got the 04 trans instead of the 03 since the 04 are a little better and at that same time i would have got the
PI 3500 stall, the j-mod,deeper trans pan and a rear cooling kit at that same time since would have been already out but i didnt know no better and kinda mad at myself for just jumping into that.

but anyways i have a motor and tranmission fully rebuild units and have bob bob bell install them motor has 10k on it got 13 months again and the trans got 9 months ago n got something around 8k miles on it but anyway

steve calls today and said have you been running this car hot and i say no steve i would never and i always watch my guages and my car has NEVER ran hot NEVER and he says ok bec that pinging is the exhaust heat coming form your pipes and into the intake or somethign i forgot is exact works but causing that pinging and it blew your head gasket. theni said are you serious how it that when i never have any smoke coming out my pipes never not even on start up never have smoke coming out of my exhaust pipes. i seen a blown head gakset on my bro 5.0 and blew cloudsss of thick white smokes out of his pipes.

so i said my warranty is gonna cover that most definalty right and he said of yea, then i said i hope bec jasper is supposed to have one of the best warrantys and they stand by there products they do a 5/year unlimited mile warranty and steve said it looks like your gonna have a rebuild motor getting put back in this thing again this week.

so it looks like not gonna have a car to next week but gonna be work the long wait since getting a rebuild motor with 0 miles on it and back to brand new so im pissed now since have not drove my car in over 2 weeks im lost without my MM but when i do get it back gonna be better than ever with a rebuild motor and a trans with 8k on it

so i cannot wait to get my car back miss it soo much and sorry for the longgggg story but i just thought i would share it with you guys since i said i would keep you guys posted.

best thing is will not have to pay a penny out of my pocket at all not ever for the bills of 180.00 steve said since car had to be there for almost 2 weeks so will be happy when get it back. not a penny coming out of my pocket.

[ctrlraven]

That sucks but at least it's already there. Just an FYI you posted this in the "Welcome Forum". Might want to have a mod move it to the correct forum location.

[MM2004]

Interesting story, and you came out smelling like a rose.

Thread moved to the Shop Talk forum.

Mike.

[Ozark Marauder]

all your problems = :mad2:

not having to pay a penny out of my pocket = :D

not driving your MM in 2 weeks, and having to wait = :(

better than ever with a rebuild motor and a trans with 8k on it = :banana2:

hang in there......

[breeze]

I gotta ping in mine upon start but goes away in seconds. Not head gaskets because are new.

[marauder410]

yea this is all a PIA but when gte back in my MM and drive off the lot gonna be a good day.

have not drove it so long gonna feel like i justs bought a new car cannot wait.
