lost house power to dash while driving

[tom&berni]

On a trip in my 04 Suncruiser when my house battery power to the dash quit. This affected the cigar lighter where I have accessories plugged in and also the theater sound system. I checked all of the fuses that I could find. The batteries are OK. Later that evening, the house power came back as though an auto reset circuit breaker had reset. Where is this circuit breaker? I looked under the dash, under the step where the chassis circuit breakers are and even under the hood. Nothing appears to be wrong. Where could the trouble be?

On my coach House power(AC) is disabled while driving. DC power is not.

On mine there is a relay that energizes in the overhead that disables the power while driving. I have a fuse that if I pull it will prevent the relay from energizing.

Not sure about your coach.

Oh make sure none of your ground faults have tripped. On mine the breaker is on the outlet in the Bathroom. Make sure all your ground faults are set.

maybe something to do with the switch on the dash that allows you to chose power from engine batt or house batts for the dash. Kind of a good start point to pull that switch then check with volt meter to see if you have power there...

Thanks for the help. I have a suspision that this problem is heat related. I may have a weak circuit breaker in the chassis breaker panel. The manual reset breaker for the coach front panel does not look right. I am on the road right now and will have to wait until I get home to take it apart. Thanks again.
