6V system...12 volt to starter

[V8 Bob]

I would solve the 6V starting issue rather than complicating the electrical system.


First thing is run the battery ground directly to the engine block, then ground the body and frame from the block.


Second, use a quality 6V battery. My choice for over 20 years has been an Optima.



Third, make sure the battery cables are correct size along with good quality connections and terminals.
