My bilge pump died this year. However when i try to install a new one there is no power to the harness. I replaced the burnt fuse at the switch but the automatic and switch mode does not work. I check the boat side of the harness and there is no power. Is there another fuse closer to the battery. The wire going the fuse attached to the kill switch is the same color as the wire going into the harness but the manual sys there is for the stereo memory. I followed some of the wiring back to see if there was an inline diode but I don't want to tear out all the electrical . Anyone have this problem?

Don't have this problem, but the electrical diagram i have shows there is a 3A Fuse at the Main Disconnect fuse area (C-153) BR wire with red tracer to bilge pump (that is energized whenever the battery is in) it is powered even when the main disconnect is in the OFF position.
Electrical diagram also shows there is a diode (C-220) between the Bilge Pump switch on the console and the Bilge Pump (in line on the BR wire. Don't know where the diode is, but guessing in the console?
