So recently I’ve been thru 3 alternators.
I had my OEM one (12 years old, go out) I had 2,000 watt sound system on 80amp alternator. Pretty sure that killed it.
Got a remanufactured one off amazon , sold the sound system. Got a new battery too just in case. And after 2 months, when the car gets super hot after boosting a couple times. I would say around heatsoaked temp where the turbo is just hot as hell, the alternator goes to 12.2v at stopped light or while I’m pressing the pedal. If I let off the volts jump back up to 13.7v (according to the turbo timer)
Anyways since it wouldn’t stop going to 12.2v I returned it and just bought a brand new alternator instead of remanufactured
3 days after getting it the exact same thing, runs fine while engine is cool/warming up. Once it’s operating temp the volts go wacky.
In park the volts are normal.
Coasting without foot on pedal normal.
Stopped light, or barley pressing gas = 12.2v
Hitting the gas normal volts
So now I’m starting to think something is draining to much, or something is wrong electrically. Any advice on what I should check or solutions?
