Originally posted by chpthril View PostThe auto bilge is wired directly to the battery and the manual side of it is wired to the switch. Since its a single pump thats auto via a float and manual via a switch, it has a single ground that probably terminates at the ground BUSS on the starboard transom.
The switch will probably have 3 wires: one is a ground for the switch's back-lite. There will be a B+ and then the switched 12V going out to the bilge.
No, the light in the switch will light if there is B+ and ground on the switch and has nothing to do with what actually gets to the bilge. What is the light in the switch doing, this will at least tell us something.
