    Hey kids
    Working on my new best friends Post 42.
    Owner not here but I think 1999/2000 vintage.

    ProMariner, 3 chanel, battery charger mounted way forward/port in the engine room. Had strange issues till I made a strap from the charger negative terminal to the gen-set battery negative post. Charger works great and all batteries charging.
    I'm sure there is negative lead fuse somewhere,,, WTF is it?

    So, I hand traced the negative cable from the battery charger to the port terminal interconnect strip. No Fuse as thought or as should be.
    Ya think this could be an issue? Charger lead, smaller cable, #3 from the left.

    Makes you wonder what the rest of the electrical system and connections are like.

    Amazing, the stb side buss bar looked great.
    I suspect the port engine exhaust had been leaking on this for a while.
    New dump cans on both engines now.
    Some copper tubing a lil higher (than in the picture), was green also.
    New PSS on the shafts also, Terminal plate could of got wet from shaft spray.

    All dry now, just some things to clean up.
    It's a boat, never ending..
