Hi you'll I don't post that much here, well i've been having problems with my car it's a 2001 Z28 the problem is my light and every thing that lights up flashes when I hit the gas and a lil when its at idel I check my alternator and it passed so it wasn't that so if any one can help me I would appreciate it thanks.

 

Thats odd!

 

Sounds like the voltage regulator to me... which is part of the alternator. Did you pull the alternator out and do the test at the local auto parts store?

 

i'd say voltage regulator too. or possibly a ground problem?

 

I have a 99 TA and mine does it too. Blip the throttle a bit and the lights will flash. I also notice it when I shift while driving at times. Sure would be nice to figure this out.
If you come up with the solution, please post back here so that I know what to check.

 

Are you talking an actual on-off flashing, or just a pulsing, where they never turn off but just get dimmer then brighter?

If it's a pulse, I'd replace the alternator. That's what happened to my '02 Z when the alternator went. I replaced it, and all was perfect again.

 

it wouldn't be a bad idea to replace your battery/ground cables with larger gauge ones when you replace the alternator as well. my headlights will dim slightly when the rpms drop or when i had my sub turned up.
