Im restoring this old boat and am running into a phantom electrical problem. Some gauges aren’t working, but in investigating, I’m finding that their power supply is fluctuating and maxes out at something like 11.2 volts with the engine off but a fully charged battery. The bilge pump is new but only sometimes can pump strongly enough to clear the bilge, so I’m assuming this is a power problem too. Where should I look to try and track down the source of the difficulty?
thank you!
