Re: Battery ground to hull?
Posted: Sun Mar 19, 2017 8:06 pm
Made it out to the boat this weekend and cleaned all the super corroded connections. I have to replace a ton of components because of snapped or disintegrated terminals.
Question: After disassembling the ground system to clean, I see that the battery only grounds to the engine block.
There are a few circuit ground wires running to the engine block but not directly to the battery.
An old car guy told me that cars of that vintage always grounded to the block. But the resistance could be causing problems and maybe the engine rusts as bad as it does because of the return?
Is this correct? There is no hull ground either (I see one white wire (12gage) screwed into the frame but that is it.
I see the bulk head ground instructions above but hesitated when I read that if currents run back through the hull, it makes corrosion really bad.
Should I still run cables to the bulk head?
Thanks,
