After I installed my motor I developed a problem with my lights going dim and bright when I am driving at night. The car never used to do this even with 2 amps and a decent stereo. When I was driving the car in November I didnt have the stereo installed, and the lights would flicker at night. Can this be somehow related to the grounds? I doubt its the alternator because it was fine before I pulled the motor.
When I reinstalled the motor I didnt use the stock ground straps. I'm running a 4 gauge wire off the negative terminal to the engine block and then a 4 gauge wire from the engine block (on a different spot) to the chassis. I noticed the chassis ground started to corrode a bit because I ground it down to bare metal. I think that maybe I didnt make the contact service clean enough on the block. Would this cause anything to do with the lights? I dont have any problems with a dying battery or anything either, and the grounds on the lights are all fine.
