everythings fine untill i turn on the headlights. ill hit the brakes and i just what my cluster dim and my volts will drop slightly and then when i step on the gas they will somewhat jump back up. Also when i go into reverse the draw is there day or night.
and when the fog lights are on its also noticable. i appoligize if its been covered but i could really use some pointers, bad grounds?

 

check all aftermarket wiring first, especially on the parking light circuit (red green wire coming out of the headlight switch which also runs to the radio area and illuminates the cigarette lighter). Also if you were ever in an accident that affected the front bumper and headlights it can make the headlight motor stick and continuously drain the battery.

 

no front end accidents but my headlight motor for the passenger side is sticking from time to time but that was a fuse i believe cause i went through all of my fuses inside. i just figure it has to be something with the tail light wiring.
