Hi, I have a 93 chev burb 4x4 Pretty sure its a ground prob on the 350 motor. I also have a plow on it. New battery and plow motor and alt, but still totally dead even with jumper cables or charger on it. checked the main ground from battery to block but was told up to 6 grounds on the 350. Can someone give me an idea where some of the other grounds are. would be greatly appreciated
