2011 Fleetwood Storm no 12V power w.o AC

Thanks, Mark. A few additional details: running the engine will charge the house batteries as you mentioned. However, running the engine does not feed the 12 v lights and other items. They are only working when 110 is fed so my lights are working now bit, as you suggest, the house batteries are not getting charged from the 110.

I noticed that now, even when the disconnect is turned off, the light that suggests it's on is still lit. Additionally, in the past when I turned off the disconnect the steps would not activate - now they do.

Re fuse, it was a 10a fuse but of course that fuse is not labelled so I have no idea what it was. I can state with confidence I didn't blow the fuse messing with any wires. That said, if I lost a ground somewhere it wouldn't surprise me though I think it's more likely a solenoid or some such went. Unfortunately, they don't give us any wiring diagrams with these things so I'm guessing I'll have to bring it in for service. Sigh.

Running the engine charges the H-battery only. It has no connection to the 12v,dc, circuit so it will not power 12v items as you noted. So the house-batteries must be connected to the 12v,dc,circuit to have any of those items working when not plugged in (not happening). That includes operation of the air-conditioner (thermostat needs 12v,dc). The LED light should light when plugged into shore-power. It only means the 12v,dc, circuit is energized. To show the batteries are connected the LED must light when the disconnect switch is pushed to connect the battery-bank when not plugged into shore-power. No lit LED means the solenoid (solid state type for our Fleetwoods) did not connect when the rocker-switch was pushed to "on". Solenoids can sometimes stick so cycle the switch on and off a number of times. If the battery is low starting the MH engine will supply more voltage to the house-batteries and may help make the solenoid work.

Until the solenoid gets checked out and most likely replaced you can get 12v,dc, if you are plugged into 120v, ac, shore-power but obviously the batteries are neither being charged nor discharged since they are out of the circuit. I take it you must have used a portable charger to recharge the house-batteries right before this post. You should do that again to get them back to 12.7 volts. It may take 12 to 24 hours.
