More BS Alternator issues I cant figure out

Officially defeated.
He's coming to get it tomorrow.
I can turn every single accessory on and the voltage will only drop to 12.5...from 12.6


Wtf
 
Is there any chance something is draining WAY too much all of the time? It would almost have to be a sub and amp I'd think. Does he have a stereo system that you could take off line?

If he does, see if he has a capacitor that might be robbing all the extra juice.

Sorry brother. I know your giving up, but I'll keep thinking on this end.

Something I've never tried before. Testing the alt output with the battery wire disconnected? (Nothing to draw) I'm stretching here..

Not pretending to know what Zack, JB and others know about these cars but could it be a grounding/ground strap issue?
 
I have done everything.
I've ripped all my harnesses apart....twice.
I've swapped alternators. I've verified continuity from the alrernator pigtail to the PCM.
I've swapped pcm's
I've checked fuses. The battery light is not on when the engine runs, but the light works

And yes my voltmeter is fine
 
I would think if the alternator check out in both directions at the shop then problem from car side...
The security/auto starter systems can cause phantom drains... problem may lie there...

I would be checking voltage draw. I'm thinking the alternator is under a heavy load.
 
^^^what he said^^^
An induction type ammeter could tell you if your drawing a load with systems off and car running. Results could be compared to your maruder. Since no fuses are reported blown the draw would be associated with an a high amperage circuit.

If there is a draw then start pulling fuses until........

You could rent the ammeter or maybe someone you know has one.

I can't find anyone to give me a lead, or advice, or a similar experience.

Lemme guess....it needs a brand new Alternator to fix this right?

Trust me I'm mentally exhausted from all this

This takes the fun out of it that is for sure.

Do you want to speak with Jeff? He is a pretty good diagnostician and even worked on a Marauder once.
