Yea, mine does the same thing? Could it be the voltage regulator?

Re: Dim @ Idle ?
Mine do the same thing. I always attributed it to just being an old vehicle and having a weaker alternator and no computer telling my truck what to do.

Mine do it as well and so do my headlights.

Re: Dim @ Idle ?
It's fairly common on older vehicles.The draw of the electrical system is usually enough to draw down the system at idle.Probably the headlights do the same thing.That is why there is a FAQ on upgrading the headlights using a relay.

Re: Dim @ Idle ?
Even after the upgrade, you'll still have it a little, but not as bad.

Re: Dim @ Idle ?
If you're going to do the upgrade go straight to the CS130 alternator from a gm car or truck from the mid 90's.I did mine that way and dont have any dimming at all.The Cadillac and the buick park ave. have 140 amp alternators! There is a link but I cant think of it right now,It may be MAD electric or search the threads. You wont be sorry. Also what seems to complicated on electronic ignition? is it HEI?
