if your gauge lights arent kinda of on when you have them off then it's not your altenator..

Uh, what?

My gauge lights go dim when the cars RPMs drop low at idle. I don't know if the low voltage is caused BY the low idle or is CAUSING the low idle.

Only time something similar happened on my car was when TPS was faulty.
