In addition to the + &- connections there is a ground lug. On a automobile I would connect the ground wire to the block. I believe that is the same with a boat. Am I right?
Sounds like a worthwhile project that I might want to do.
Pictures of the project would be appreciated.
Equipment intended for auto/truck usage often come equipped with a separate ground.
Test for continuity between the negative wire and the ground wire. If there is continuity, then just connect the negative wire and leave the ground unconnected. If you feel compelled to connect the ground, then the engine block.
