Default Need Electrical Help???

When I start my engine, the gauges and lights flicker but when the car is in the on position (not started) nothing is flickering. Figure it might be a ground issue but then didnt know because it doesnt do it when the car isnt running. Let me know what I can do. Thanks

you probably need a new alternator. voltage regulator is going bad.

what will cause that? 63k on alternator and have had it checked multiple times, not saying it isnt going bad. It seems like something with the alternator has to be it. Thanks for your help

its the electronics in the alternator. sometimes they can still test good but be faulty. along with the battery the alternator powers everything in the car. if you have flucuations in voltage or current it will cause the flickering lights.
i had the same problem on my factory alternator at about the same mileage. i replaced it and it solved the problem.
