My battery light and brake warning lights are flickering on and off? What causes this? I had my alternator replaced a short time ago. It seems to happen when i accelerate and wind the windows or use the electric accessories. wierdness. what causes this? wiring maybe?
 
I've noticed on my car that sometimes when the alternator hasn't really fired up yet (i.e. probably low system voltage) that several dash lights will come one. ABS, Brake failure, maybe another one. When I rev it up and the voltage comes up, they go off and stay off.

Dunno if that's related or not. But a first check might be to use a multimeter and see what the voltage is when it's running.
 
alright il give it a check. I have revved it up and it lights up more and then goes dim. I only got the alternator installed a few months back..... yikes i knew i should have done it myself.
