Hi ALL-
It's been a bit since I've been on, life is funny that way-
Not much to report on the GMC up til now, life is funny that way too-
But I was out there this evening, as I've been using it as a workspace of late...
and all of a sudden, all power was lost.
no AC, no DC.
at the same time, like a switch. It's currently plugged into shore power at the house, and the breaker didn't trip. Cord has a light, so I know there is power to the coach.
I'm not in "GMC MODE in my brain, as I haven't been futzing with it lately, and I'm stumped.
Any ideas on where to start?
The AC was on, but no lights, and the floor lights and DC overheads all went out at the same time.
Thanks for your help, and I hope everyone is healthy!!

You must be running on the battery charger, whatever type that might be. You may have tripped the main breaker in the coach. You'll need to start there and see if you indeed have power in the coach. It can be many things including a bad adapter after your cord if you are using one which I assume you are. Just work your way in from where you know you have power.
Good luck, Hal

Chase the AC problem first. When you are plugged in to shore power the shore power 120 VAC supplies 12 volt DC power through the converter to the coach. It also charges the DC house battery(s).
So fix the AC FIRST.
1. Reset ALL of the AC circuit breakers.
2. Remove the circuit breaker panel cover and using your meter start checking for voltage into and out of the various circuit breakers. Do not overlook the white wire neutral bus and wires too.

Hi-
Just wanted to update-
I ensured the shore power wad all solid to the coach
Opened up the converter, and Lo-
It was a fuse.
Phew! Electrical gremlins are one of my biggest fears. That and squash.
Thanks Yall! Now to figure out why it takes a bunch of gas straight into the carb to get this thing started everytime.

Adam,
To start Chaumière after sitting a long time, pump the throttle twice, crank about one cycle (8 compressions). If it didn't light, two more pumps and go again. At this point she will just about always fire. If it has been cold enough and long enough, maybe once more. That is rare.
I think you should lift the carburetor off the manifold and look at the bottom. I known issue with Rochesters is the plugs in the bottom of the float bowls. These can leak so slowly that the fuel fumes are not pronounced but they will drain enough to make for very hard starting.
If you are not positive that they are not leaking, leave the carburetor upside down on the bench and find a thin epoxy to pour into those plugs. I have used this trick a couple of times now and it has always helped. One of those was so bad that we could see it leaking on to the intake before we took it off.

Back in the day anytime we'd do a rebuild the JB Weld would come out and the plugs get covered. Automatic on all our rebuilds of Q-jets. Don't know how long that stuff lasts but never did have a come back on one.
