Shower Pump Fuse

[Brian John]

So the shower pump quit working on the R-31. I looked for the fuse but could not locate one. On the R-31 Dash Fuse Block #2, left side 2nd fuse down is labeled Shower Pump, except there is nothing connected to this location. I do not have 12 VDC at the pump in the V-Berth (float switch works, pump is defective). I need to locate this fuse. I have checked all the fuse blocks and am at a loss for the location of the fuse.

I found the blown fuse. When I checked the voltage at the shower pump (with the pump disconnected), I read 11.86 VDC. This told me that this circuit was running through another load. I checked the fuses one more time in the Aft compartment and found 11.86 VDC on the Bilge Alarm fuse, a 7.5 amp fuse. I replaced this fuse and 13.56 VDC at the fuse and on the conductor for the shower pump. I decided to power the shower pump as shown on the schematic for the boat to the fuse labeled shower pump. This required removing the refrigerator. While the fridge was out, I installed some pull lines to simplify and future wiring I may add, such as a backup camera.
