hey all. i installed my turbo setup 3 weekends ago. this is a problem i NEVER experienced for the 2 years i've owned the car but i just noticed it this weekend. i haven't driven the car at night in a while(few weeks)
so i was driving and i asked my friends if they just saw my headlights dim. so we were paying attention and sure enough my headlights would dim or go brighter. and it seemed to coorelate with throttle. like part throttle they would dim, and then no throttle and hit the brake and they would be bright. then i noticed all the interior lighting were doing the same exact thing. but then it would do it at constant throttle too. it would either go dim or go bright. and also sometimes it wouldn't change if i went from part throttle to no throttle.

dying alternator? loose grounds?

let me know what you think

Did the charging system light (looks like a battery in the gauge cluster) come on at any point?

 

nope no charging system light

 

I have the exact same problem, I always assumed corroded grounds were the cause, but i'm really no electronics expert... i would assume it couldnt really be the alternator, because quick load increases like that would just be handled by the battery, and as long as it was charge I dont think it would be an alternator problem.

 

possible alternator problem, need to check what the voltage is at with a volt meter. Check it at idle, should be over 12 volts.

 

will do. im at work but i'll let you know what it reads later
