Hi everyone. Chomping at the bit waiting for nice weather in CT. Im going to install a galvanic isolator on my boat as I was unimpressed with the zincs being totally gone on haulout. Ive discussed the issue with many of you and batyards also. My question is: does anyone know where the main grounding plate for the 115 a/c wiring is? She is a 1984 360 Commander with twin 454 mercs.
Dan:
I am not sure this will be helpful. I have two grounding plates on my commander. One on either side of the keel between the stringers in the engine room. There is also a flat, woven grounding cable bolted down to one of the bolts that come through the hull on each of the grounding plates. All you will see are the 4 bolts sticking up through the hull with this flat cable attached to one of them. Ususally on most of the boats I have seen, they are very close to the area near the engines. You may have to look under your engine also.
