My buddy has a '55 Chevy hot rod. He had lighting issues and kept blowing the $100 infra-red MSD module. I took a look and the only ground was by accident through his clutch linkage. We ran braided mesh grounds from the engine to the frame, from the engine to the body, from the frame to the body, and a dedicated ground from the battery to the MSD distributor. End of problems. You can't have too many grounds.
