Need a Ac electrical diagram for pumps under galley floor for a 4207, 1988,

Thanks for the excellent insights, as you can tell, I’m an electrical dummy and I’m outside a little town and can’t schedule a marine Ac electrician for two months. They’re all backed up. The Ac power and fans will work on generator power but the pump doesn’t. However, neither work on shore power. The black and brown wires which are next to each other with caps are from the same sheathed run. The brown one on left is separate. The red and black wire is heat sealed to the orange and black which runs a altunas remote intake pump. The Ac pump to the right has a black cable running into the rectangular junction box.

Correction: The separate brown wire is actually to the right of the sheathed black and brown.

Yup that is a lot of confusion there, I see your problem, There is what appears to be a bilge pump connected to a filter ???........the dead ended wires, seem to be large gage from the pic as if they went somewhere a some point.

Unfortunately you are going to have to trace as best you can as it may just be the circuits are not complete due to the mods there, you can see wire bits in the bilge. A good multimeter and some extra wire to check continuity along where you figure the wiring goes, there has to be a source and a good ground for all those 12vdc circuits.

Sorry can't be of more help.

if the pump doesn't run on shore or genny power. maybe the pump is bad? Check for voltage at the pump.

Did you ever get this figured out?
