At about 3,500 rpm my Alternator "amp" light comes on and my volt meter drops way down. When I return to near idle (at a stop light or whatever), the light goes off and the volt meter goes to normal. Any ideas?

I've been having this problem only since completing a top-end rebuild after a little cooling problem. It happens whether the car is cold or hot. Seems RPM dependent. Doesn’t' seem to be effected by road bumps.

I've done everything I know:

1. Checked the alternator-to-starter relay wiring...have upgraded it to a 4-gauge a long while back.
2. Checked the batter-to-starter relay wiring and replaced that cable due to a deteriorated battery end.
3. Checked my main ground,
4. I just replaced my starter relay with a new Ford unit.
5. My battery is less than 2 months old.
6. I have a 6-month old PA-Performance 130-amp alternator.
7. I've disconnected my Crane HI-6.
8. My VII electric fan has no effect on the problem.

Thanks in advance.

Follow-up

Just a follow up for anyone curious.

Well I swapped on a Autozone reman. alternator and the problem is gone.

I still need to follow up with PA-Performance to see what they will do for me regarding my 130Amp failing after 6 months.
