Fresh water pump 2016 cb

[Gwkessel]

Had shore power issues causing multiple house breaker trips. Power issue restored but was unable to turn on fresh water pump and main cabin lighting. All cabin outlets were good.
Also raw water wash down pump would not activate when selected.
Any ideas where to troubleshoot and restore. Power good charger/inverter good.
Thanks,
George

Those items should run off of 12V so shore power not necessary. House battery switch or fuses.

Thank you, fuses looked good and house batt sw turns on all other options. Perhaps a tripped relay,not sure how to reset.

The DC problems shouldn't be related to your shore power problems unless DC wiring got messed with while troubleshooting the AC issue. Because you have multiple supply problems from the DC panel, but not all of the loads on the DC panel, my suspicion would first be the ground side. Check your battery cables, specifically where the main ground connection goes to your panel loads. If you still can't figure it out you may need to check the wiring at the water pump. Cut into the splice with the breaker off, turn breaker on and see if the positive wire gets power or not.(Using multi-meter on DC Volts with red lead on positive wire and black lead to a known ground/battery negative) If you have power to the positive wire at the pump, then your problem is in the ground wiring between the battery and the inoperable loads.

The shore PWR issue was only a loose plug in connection at shore pwr pedestal. Switched to another pedestal and connection was solid and power restored without any further trips. Water pump and cabin lighting were all working prior to taking boat out for the day. All occurred upon return after I turned on shore power breaker and plugged in to boat. That’s when the main 30 amp house breaker would trip before and /or after attempting to put charger/inverter online
Thank you
