Electrical out in back half of Airstream

[gitrokr]

I have a 1980 excella and the power to the back half of the trailer has gone out.

All was working fine until recently. There was a blow dryer plugged in to a 110 outlet that I think was the culprit.

12v lights and plugs in the back half have stopped working. I tried flipping the breaker but that didn't solve the problem.

Could it be a blown fuse?

Replaced a couple broken fuses, but that didn't solve the problem. 12 volt lighting and outlets in the rear half are still out.

I don't think the blow dryer could have affected the 12 volt system in most reasonable circumstances.

Look those 12 volt fuses over again. A test light is better than a visual.

I reread you original post;; questions,

The 120 AND 12 volt are out in the rear half?

Was there a burnt smell when the blow dryer was used?

[J. Morgan]

The only way I can think that the use of the blow dryer would cause the 12v to go down is if a 120 wire burned and as a secondary effect burned a 12v wire that was very close or touching.

This would not be a typical occurrence but possible.

120 wires seldom burn in the middle of a run, usually this happens in the jct box .

If the circuit for the blow drier is the same as the one for the converter, then the 12 volts will be out if your battery is low. Check the large fuse from the battery. There may me one on the negative side.
When resetting circuit breakers you must flip them to the off position, then to the on position:
