Today I went to check out my noisy furnace and found there was no 12v power. I started generator and all was well again but after shutting down generator no 12v power. A quick check of fuses offered no solution. Not sure where to start tomorrow troubleshooting. Seems like this has happened before but memory is failing these days.

Are your batteries dead? What is their voltage when the generator is not running, powering the charger?

I do believe that the generator starts/runs off the house batteries, so I suspect the batteries are okay.

It seems that the converter/charger is also okay if you had 12V power when the generator was running.

About the only thing left are the DC circuit breakers in the bottom of the BCC box.

Does the Pace Arrow have the cut off switch by the door? Maybe somebody hit it by accident?

Dinner and dark caught me so can't answer most of these questions. I didn't have 12v for certain with generator running. I'm pretty sure all 12v was off. I would bet batteries are good but that is where I'll start tomorrow. Battery disconnect switches are above door. I tried them both ways and still no 12v. They have to be on, both aux and main switches, right? Didn't find and breakers tripped on main board inside coach. Coach was connected to shore power and unplugged to move for a wash job. Besides there is a solar charger that indicates it is working. Taking it in for slide maintenance soon so this may be another item on list unless something is discovered. Did check out furnace and it appears blower motor is shot, sounds awful so I will be shopping.

What are you referring to as a BCC box? I have a CB panel under the fridge that controls the house, I think. All I have under the hood are fuses.

There is a box mounted on the outside firewall under the hood that contains fuses, relays (solenoids) behind the circuit board and two DC circuit breakers in the bottom of the box.
They look like this...
Press the little plunger in the base of the breakers.

Thanks for reminding me about these breakers Old Bounder. Memory is getting a little worse but when you jogged me I remembered. That was the problem.
