wtf is up with this?

i remember on a ton of mustang carfax's there was always "electrical system serviced" for the new edges i looked at

i guess im about to be one and this is a common mustang problem

what is is guys?
help plz

 

you might be getting a poor connection from your terminals to your battery

 

check your alt. voltage sounds like the alternator is going out

 

but it doesnt really flash, it just comes on for a minute or so at a time...every so often

 

oh yeah

i had it checked at autozone

he said it was fine

 

The internal voltage regulator in the alternator may be intermittedly going bad. You said the light goes on every 20 minuets or so. I doubt the guy at Autozone ran it on his bench tester for 20 minutes. Just a thought.

Edit: If you could put a voltage meter on the bat. when the light came on, that would help out.

 

I had the same issue for a while. I sent it back to PA Performance. They checked it, sent it back w/ NPF. I put it back on, was fine for quite some time then it started doing it again. I called them, sent it back again, they o/h'd it. No more problems. I can bet your alt is on the way out. Something is happening internally that is intermittent causing the problem.
