Mosin Posted August 6, 2008 Report Share Posted August 6, 2008 Not sure if it varies from vehicle to vehicle, but what do PCMs/ECM's handle before they get fried from use of to many volts? Like would 14.4-15V fry a PCM? Quote Derp. Link to comment Share on other sites More sharing options...

As far as I know. No. I have peaked mine at 15.6v before and it still runs. Although it is a little older.

Little older? your talking about the Bronco in your signature right? Like my car, has an externally regulated alt. pre-set at all RPM's and whatever. Would to many amps from an alt. kill it?

Would to many amps from an alt. kill it? Yes the Bronco II, same as a Ranger. Amps? No. It's REGULATED so if your battery is getting full, it will back off. Volts. I'm pretty sure 16+ would kill something. Quote BigPimpin91's Banging Music Link to comment Share on other sites More sharing options...

No. Don't quote me on that though. If the alternator is made for your vehicle, I'm pretty sure they had the regulator in mind and worked with it. Worse comes to worse, hit up MLA, see if they can help you out. Quote BigPimpin91's Banging Music Link to comment Share on other sites More sharing options...

Stephen Posted August 6, 2008 Report Share Posted August 6, 2008 i had a 07 trailblazer loaner car and it would get to about 15.3 on a cold startup Quote you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

MECHMAN Posted August 6, 2008 Report Share Posted August 6, 2008 i had a 07 trailblazer loaner car and it would get to about 15.3 on a cold startup You will be fine at 14.9, but anything higher than that and the battery will start getting cooked if it's an AGM type. 15.5 is OK if it is a flooded battery. A High Output alternator will not hurt anything as long as the voltage is set within those peramiters.
