Replacement Alternator

[95chickn]

Could I use an alternator off any crown vic? I would have to order Reman one and it would take 7 days, I dont want to wait. There's plenty of CV's at the yard...

[RubberCtyRauder]

No, marauder needs 4g, CV is different

[FordNut]

Seven days? NAPA, Auto Zone, or Advance should have one, maybe not in stock but next day.

[fastblackmerc]

Correct... a CV alternator will fit but won't work. You need a "4G" style alternator.

RockAuto has them. I bet you can get it in 5 days or less if you pay for faster shipping.

I definitely would not get an alternator from Auto zone , there parts are garbage.

[blkZooM]

I got one just sitting around how much do they normally go for?

Have it rebuilt at a local shop.
Turn around is sometimes as short as 2 hours, and costs around 80-100bucks

This ^^

If you get a "new" alternator it will be Chinese junk likely to fail and leave you stranded. Put new bearings and brushes in your existing unit, or have an alternator shop do it for you. Re-use your existing internal regulator module from Ford, it is decent quality compared to the garbage at the parts stores.

Is this right? It'll bolt in?

[FordNut]

No, it won't work

Not to revive a dead thread but has anyone tried the 220 amp alternators that dbelectrical offers?

I seem to recall someone saying that they installed one of their products and they had an issue with the belt not fitting on the pulley or that their belt suicided on it ? Does this sound familiar to anyone?

[FordNut]

I'm using a high output DB.

I'm using a high output DB.

Going through older posts, I think it was JustBob that said his db unit "fell flat on it's face"
Any issues and how long have you had it on for ?

This is the alternator I am installing in the Rodder :)

Let me know how that works. I'm never confident about an eBay purchase that has no core charge or any mfg markings

I bought that same alternator a few months ago and I was not happy with it due to very erratic voltage. I returned it the same day.

That's because they put the wrong kind of regulator on it.

Do the 4g alternators have external regulators?

[FordNut]

No. They have one that is a simple off/on and they have one that is PWM controlled by the PCM. Sort of like a returnless fuel pump control signal.

[SOSA03]

all three auto parts retailers carry the same brand in starters and alternators DELCO REMY

Mine was only the regular output, but yes, my DB Alt. and starter both failed immediately after the warranty ended. In fact, the starter solenoid grounded out internally and started a nasty electrical fire.. Others here have had great luck, me not so much.

I just went thru six weeks of hell with my alternator. It went during a snowstorm which to say the least sucked. I replaced it with a remanufactured alternator I got direct from Ford (ordered by vin) price not bad at $140 wholesale.

After it was on and warmed up the voltage started going crazy..up and down when stopped at lights, low enough to drop the RPM. I thought maybe the pigtail at the alternator was causing a problem as one of the wires felt too flexible, replaced it with a Ford pigtail..still no good. OK I figured that it was bad right from Ford so I exchanged it for another...same thing?? So I had them get me a third one which after installing did exactly the same thing.

By now I'm getting pretty pissed, and went with my gut which I should have done in the first place I found and bought a used on from car-part.com put it on and just like that problem solved.

I don't know why Ford had to make the regulator different on the Marauder than the Crown Vic or Marquis, but that really screws up getting a working alternator for our cars.

I hope this helps anyone in the future when replacing alternator

I wanted to thank you for posting this, last week my alternator went out on my marauder. I knew i had read THIS POST, and i knew to go with your sound advise about car-part.com So i checked car-part.com and there was a shop locally that had it. 53.00 out the door, then i returned a v6 buick alternator and got my $10.00 core back. Out the door for 43.00 and i kept my original alternator!
Local shop wanted 150 to repair, parts are over 100, and new is 175 plus tax.
So i went on ebay and bought the 33 spline tool to remove the clutch :)

Thanks for the suggestion, i appreciated it!

, Should have just took Zacks advice
