B733

I have the series parallel switch in the top illustration, the red illustration is a different switch. I’d like to get it right so I don’t need firemen’s fund insurance.

That is a positive ground, I want to make it negative ground and still use the 24 volt starter,

Want to convert 12/24 system on a ‘57 LST from positive ground to negative ground and keep the series parallel switch. Any help out there, diagram would sure help.

need help with wiring diagram. need diagram for 1957 b73, or somewhere about there, 12 volt positive ground, 24 volt starter, Cummins powered, with circuit breakers instead of fuses. got most of harness built need diagram to finish new harness, old harness copied as far as i could. had trucker/electrician make mods to it over years. engine going back in frame now, chrome sent out, cab ready to paint.
