my lights dim when i hit the brake.

i searched around and some people have similiar problems, but their charge light is on. my battery harg e light is not on, which makes me think its an alternator problem. i wanna make sure though, i dont wanna buy a new alternator and find out its the battery. thanks

Either missing or bad grounding wire(s) in the engine bay. You'll find plenty of posts on that subject and their resolutions. One of our easier and cheaper fixes.

This is very common with RS's. Having a weak alternator (70A) causes this. If you have a system in your car Id suggest getting a Cap.

no system as far as i kno. just a head unit, although the speakers r very good for stock speakers (that is if they are in fact stock). the lights dim, and slowly goback to normal. maybe it is a weak alternator. wouldnt an alternator cause more problems than dimmed lights?

No problem, just a flaw in the design. Alternator normal. If it worries you so much, first thing a ground wire kit, and then let us know.

Alternator is just underpowered... and our grounding system sucks.
