Alt turns on and off at idle WTF???


Recommended Posts

Posted

My alt - or rather my regulator seems to be turning on and off at idle and it's really frustrating me. Sometimes it will cause my 4 channel to go into protect for a split second.

I have an externally regulated DCpower 270XP

It only does this when the car is in gear AKA low idle. Not when I'm driving, revving, etc. I can bring the revs up to 1000 in gear at a stop and I won't have the issue. The only time it does this is in gear.

Relay is getting power, and the regulator is seeing power. But the regulator intermittently puts out power

Any ideas?

I have a video uploading now.

How is the alt excited??

Field wire comes off the regulator and goes into DC's plug on the top of the alt

Only my 4 channel protects because it's only stable up to ~16, vs. my sub amp is stable to 18.5
