Our Mastervolt 8 kw generator recently started spewing white smoke/steam. We decided to pull it out of the boat and check it out. We found a lot of leaky raw water connections, a leaky raw water pump, and a mangled impeller. (Yes, we hunted down all of the pieces and put Humpty Dumpty together again.) We also found a lot of crud built up at the heat exchanger. Anyway, we are hoping that fixing the raw water circuit will solve our problem. In the meantime, we are busy sand blasting and painting parts, rebuilding the pump, and getting the heat exchanger cleaned out. My question is, when we are ready to fire it up again in the garage, do we need to be worried about the electrical not being hooked up to anything? All of the control wires are still in the boat along with the panel. We are thinking about just hooking it up to a battery and providing cooling water. We figured we could use a jumper from the stop solenoid to shut it down. Anyone with experience in this area please let us know what you think. I don’t want to end up frying the electrical part of the generator.
