Do you have a system in there or something to make your lights dim? if you have a system eater fix your ground on your battery like take a 4 gage wire or something around that size and make it as short as you can and take and run it off the neg of battery and ground it on your car more so that the neg can get back to the battery better or if you are running a system that is really powerful then you may want to just buy a compasator or something i have had 2 altnadors go out on me then i did some asking around and checking on the net and well i have had no problems sence then. if you have any other questions then just respond.
