Re: [electricboats] Grounding.

This is the article I was reading, but not sure I understand. Been a long day and I am not at the boat to poke around, and put a face to the name as the saying goes.

Thanks. In that case I am keenly awaiting responses from more experienced folks as well :-) 

If the though-hulls were not bonded that makes sense to me, or if the connections were poor. I'm not sure how it would cause that otherwise, but the fun in this whole process is learning.

I read an article that said not to do that particular thing because it would cause excess electrolysis on that particular through hull.

My understanding of this area is rudimentary, but I believe the goal is to eventually connect the ground to the bonding system that probably connects most of your brass or bronze through-hulls to your sacrificial anodes. I attached mine to a nut at the base of one of the through-hulls. 


The article discusses in more detail and I'm not sure I've yet arrived at the correct solution for my boat and plan to double-check everything at the next opportunity.

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?
