yep, mine is wired that way. when my coach battery was out but engine battery was full, i had to start engine first and let it run for a few minutes to charge up the coach battery then i could start genset. once genset was up, i turned the engine off.

Genny under load

Just put back my house and chassis batts after 4 months in storage. My understanding is that to exercise the genny it should be under load. So if a/c switches are off no draw is made on the genny thereby defeating the purpose of running it monthly.

If your generator starts (and runs) from the house batteries, just make a small jumper wire with alligator clips and jump from the chassis battery side of the boost solenoid to the pick coil.

If that's not possible just use jumper cables across the disconnect solenoids.

There's always a way.

When you run the genset you need to have it under a load to properly excerise it.

If you're looking for a load, fire up the microwave. It's not a huge load, but it's pretty significant. Many people also carry electric heaters on board. Maybe fire that up as well?

Jump the house side to the chassis side and you have the problem solved. I would turn off the inverted charger before doing anything as there will be no house battery and I wouldn't want the alternator and house charger on the same time. I take it your rig is gas, if diesel let it set the winter without start, unless you drive it for an hour your not getting it up to temp. Use the heatpumps to load the gen or take a couple portable heaters along. Should run the gen monthly, not for the motor but for the Electical side to drive out moisture.
