No 12v power

We had a power outage last night while our 2010 Bounder was plugged in and now the coach 12v is completely dead. The unit is unplugged and the three 25amp fuses for the power converter are fine. I have also verified that the thermal couples for the chassis battery are also fine. Is there some type of reset on this unit that I haven't found.

Near the house battery there should be a series of resettable circuit breakers. One of them has tripped. The buttons are really small and hard to find, but believe me there there. Start at the battery and follow the Positive lead till you find them.

I traced the line from the positive lead and it appears to go directly to the load side of one of the thermo couples that are next to the chassis battery. Could the resets be located somewhere else. Thanks.

Thermocouples are used to measure temperature. I think you are using an incorrect term to describe the DC circuit breakers that are attached to the postive battery terminal. Check the unit again to see if they have power on the downstream side of the system. JM2...

I did check the downstream side and have 12v there. There is also 12v at the coach batteries. A little more information, on just 12v supply the luggage compartment lights and entrance step work but no inside lighting or refrigerator. I checked all of the fuses in the panel under the refrigerator and they all look fine. I'm really scratching my head on this one.

Also, no fridge or lights when the generator is running.

You cannot just LOOK!!!!!

You MUST use a VOM to actually check them. Fuses can look OK and still be bad. Go to Harbor Freight or similar store and buy yourself a decent meter to check thing properly.

It took a little while to trace out but I finally found the resettable circuit breakers for our unit inside the battery control center. Pushed reset and everything is back to normal. Thanks 450Donn for the help.
