Default Re: New Battery Cables

An Old-Timer changed my '47 over to a 12 volt negative ground system.

I assume you have a 6 volt positive ground system. If I had your system, my negative would run thru the solenoid to the starter, but the positive ground would run directly to the starter body bolt. This is intended to give the starter the greatest "punch" possible. My body (firewall) is grounded to the intake manifold bolt next to the passenger-side head. They also added a ground from the frame to the body as some possible insurance.
