IS there anyone that knows electrical wiring on the marauder.

[bigbillybbs]

I am looking for a good power soarce in the marauder to power some units im Installing.
I know you stereo guys may have a good idea.
It will take me forever to type what i'm trying to do so my cell is 631-767-6921. If anyone Knowledgeable could give me a call at your convenience and ill explain my situation. It would be greatly appreciated. I am really bad with wiring and electrical stuff…
Thanks Bill

I have a piece of equipment that requires a 50 amp 12 volt power source. I want it to activate ONLY when the ignition is on.
What’s the best way to wire it.

Best power source is the battery. I would run new dedicated lines.

What was Rich running with the battery in the trunk?
That was a pretty sweet setup to run just about anything IMO.

50 amps is quite a bit of current! I'm not sure how accurate this page is, but it shows the minimum wire sizes (http://www.the12volt.com/info/recwirsz.asp) one would use based on current requirement and length - the longer the wire, the larger it needs to be.
Also, if you run directly from the battery, be sure to place a fuse as close to the battery as possible (the wire from the battery to the fuse is unprotected, so should be as short as possible to minimize risk of fire-starting shorts). Size the fuse according to the wire size, not the maximum current draw expected (of course, the max current should be less than the wire capacity).

If your load has a built in power control (like most audio amplifiers do), you need only connect the battery wire to the positive terminal of the load, and an ignition-on wire to the control terminal. But, if you need to devise your own power control (on-off) circuit, you'll most likely need to use a relay.
You'll need a very heavy duty relay to handle 50 amps of continuous current. I once controlled 2 electric fans with some relays - the standard 30 amp relays would burn out real quick or else the high-current contacts would fuse together, and not release when turned 'off'. I found OEM Ford relays (used in tons of old Fords, for just about everything) worked really well, for very little $.

Is it ok to tap directly into the alternator for power instead of the battery? If i am only drawing 8 amps at 13.6VDC not
Continuous draw ?

THANKS GetMeMyStogie GREAT INFO
Really appreciate it. BIG HELP

If you want accessory (key back and forward) then get the Gray/Yellow OR Black/ Light Green. If you want ignition (12 volts in run) get the White Yellow. Those are at the base of the column and are large gauge wires ("gage" if you drive GM)

It's probably not a good idea.
For one, the alternator wire connects directly to the battery anyway, so there'd be little to gain.
Next, the alternator wire connects to the battery with a fusible link, which is like a fuse, except that there's no removable capsule - the 'fuse' is a narrow section in the wire itself, so if it blows, you have to get a new fusible link. That also means you can't install the fuse size you need. If you're splicing into the alternator wire, any load you apply with the key-on-engine-off will pass through the fusible link, potentially blowing it. Which would mean the alternator wouldn't be able to charge the battery until the burnt fusible link is replaced - which could leave you stranded if it happened more than a couple hours from a repair shop (assuming the car can run for 2 hours on battery alone).

There's probably a few more reasons, but I would just say don't do it.
