Bob Why would you do this for DC? You would do that for a lightning rod termination. DC does not need a ground to earth. AC needs a ground to earth. The reason you ground to the engine is because it is a massive block of metal. Completes the loop. Ground from battery to block, ground from anything else to block or battery it does not matter.

Ground to a keel bolt if one is available.

So I removed the old diesel and am getting ready to install the electric motor. Was reviewing Don Casey's book and came across the illustration showing the whole DC System being grounded to the diesel engine block.Since that is no longer there what should I ground to?
