Mainship 390 bilge pump power

Hi Folks,

On my new to me 2000 390, the forward bilge pump and float do not seem to have power to either device. I've tested for power at the devices with none found. Does anyone know if there is a fuse between the breaker or the pump? The boat is in Pasadena MD. Anyone know of anyone who can work on tracking down my power issue?

Bilge pumps often have a double throw switch somewhere that allows you to choose Auto, Off, or Manual. These switches are often mounted with a fuse on a small panel that could be located anywhere. If you've got one of these, the fuse could be blown or the switch simply in the off position.

Morning Mr. Trolley, on my similar vessel (same year, same model) there is a four inch square molded plastic box next to the battery switches in the lazzaret. This box has a red circuit breaker and two screw in glass fuses. These are your constant power circuits (always on)for the bilge pumps. One fuse feeds the forward pump, the second fuse feeds the mid ship and rear pump. these fuses need to be cleaned and checked on a regular basis, start there, it is most likely your issue, good luck and enjoy the boat!
