If you have a voltmeter, I would start checking power at the box light closest to the A10. Starboard locker. I would also OHM the ground wire to battery and see if its open. Remember, if you check power at the locker and the ground is open, it will show no power. If it shows no power at the first locker light, get yourself some wire..(.even old speaker wire will work), run a ground from the battery and than check power using that ground. If you have power, there’s and open ground. If you don’t, there’s a power issue. Check for any butt connectors that may have a wire loose (A10 under console to locker). Also is the pump in-pump out part of the switch working? Power coming to the A10?
