This is the battery selector switch on my 1979 Grand Banks. It is probably original and it works fine. I am getting ready to upgrade the battery configuration and need to understand one thing:
Why is there a cable from the common terminal on the switch to the engine block? Does it need to be there?
Note: Feed from alternator originally went through a couple of diodes so it could charge both batteries. At some point a PO removed the diodes and disconnected the feed to battery 2. Alternator now only charges battery 2 if selector is set to "ALL"
Thanks,
