12v problem

[Jaxfishgyd]

OK,
Took a 41' Carver out today to teach the owner's wife how to drive and dock it (paid trip).
Got back to the dock 3 hrs later... Got the dock power cords plugged in... Life is good.
NONE OF THE 12V circuits work. They were when we left the dock.
They spend the night on the boat and she used the bathroom just before we left and the head worked.
We did run the genset while out. The husband had a lung transplant just over a year ago so had the AC on for him...
Have 110v at the panal and ALL the 110 works fine.
Have never seen this before... Battery charger is working....

Has to be the On/Off Both etc. switch

It's likely the 12volt master switch got shut OFF.....or......if it is ON, shut if OFF, then back ON to make sure its seated properly.

Could be a fuse or breaker! There should be a breaker on the feed to the panel.

batt switches dont' turn themselves off... does it have a dedicated house or does it use one of the start batteries? find the house batteries and follow the wiring!

doulbe check for master switch or breaker somewhere on the panel.

coulnd't have killed the batteries in 3 hours.... had to be a switch or breaker somewhere.
