Lost all 12v power

Lost all 12v power. No refrigerator, AC, furnace, tank gauges and flourecent lights. Batteries, 120v and fuses are all good. Any suggestions on what the problem might be?

I would start at the 12V load center and work from there back to the battery and power converter.

How handy are you with a volt meter? You don't indicate what year or model of bounder. That might help.

If you have no 12V power on battery or while connected to shore power, It might be a problem with the battery disconnect relays/solenoids.

Year, make and model would help us help you.

Did you turn off the "Salesman switch" by the entry door?

It's so weird being the same age as old people.

Look for a battery disconnect switch, near the door. Some are labled Use / Store or Aux Battery. That shuts down anything 12 volt, house related.

There will also be a circuit breaker within a foot or so of the house battery positive cable connection.
