It has a smaller pulley and happens at any rpms including 2000+
new 0 gauge on top of factory wiring. i have my alternator bracket grounded to the chassis. sanded everything down. my main battery is in my trunk maybe if i ran a ground from battery negative to the engine it would help?
If you mean like a voltmeter i have one in the car
i talked to them over email last night i have to call today haven’t yet though.
No, I mean when the vehicle itself controls everything that has to do with the electrical distribution. They got really popular with auto companies in the 2000's to now to keep gas mileage down and protect the vehicle if something where to go wrong.
Any ideas as to what i should do?
To me, it sounds like it's either some kind of voltage management system messing with everything or its not grounded properly/ enough. I don't know much about those cars though. I just know I had similar problems with my truck, turns out it was a voltage regulated controller
The ELD? If that’s the case, wouldn’t he just need to keep his AC and lights on while driving?
I know my alternator is internally regulated and the pcm does not control it. I guess i can add some grounds.
I know in my truck, with the lights on I get 14.7 ish, but any other time I get 13.8ish. And that's with an internally regulated mechman 370. But it's a Chevy, so I'm sure it's different than his. I'm at work right now or I'd try to look it up myself. I was just trying to throw out some ideas
