Automotive solenoids are not usually isolated ground solenoids. I would
check it. Automotive solenoids usually have the negative side connected internally to the mounting ears. If this is the case you defeat the isolated ground on your boat.

Similar scenario while we were underway. I managed to get that DC motor free and on to the cockpit floor. There were four little hard rubber covers that held the brushes in place and when I pried them open the black dust that came out was phenomenal.
I used a spray-air can (duster) and some spray electrical contact cleaner to clean it up and it worked fine for a couple of weeks until I could get it to a re-builder in St. Thomas(USVI).
