I'm beginning to think that the Airstream Interstate is not quite ready for prime time.

My take on that is the control panel is smarter than I was giving it credit for.

I agree with you if the panel can actually tell what the breaker size is that it's connected to. However I do not think the Airstream technology is quite that smart.

Lol, I don't think it's that smart either

Yeah, there's something wrong there. You should be able to toggle between 20 and 30 amps.

Stupid question here - but you don't have generator running do you? It will default to generator over shore power if running.

Just covering all bases. Mine switched pretty quick from 30 to 20 when pressed.

Just to clarify, the water heater does not run off battery power (neither 12v dc nor via inverter to 120v ac). It is a large load and can only run off of shore or generator power, just like the roof top air. Now the cold-weather tank heating pads (controlled by the red switch by the sliding door) for the fresh and grey water tanks, that's a different story. Those do draw 12v and will kill the house batteries in about 4 hours.

Ok

It happened again today.

Here's the scenario:

engines running and I go and start generator.

No problem, it starts right up and runs.

I then go and turn on AC after waiting a few minutes for Jenny to warm up.

So far so good, alls ok.

I then go shutoff chassis engine.

Now is when it starts going downhill.

After about 10 min or so of engine being off and no change in settings of Jenny. AC still running and all ok.

THEN, BAM everything shuts off. CAN'T RESTART !! ALL DEAD.

Only way to restart is by starting chassis engine again. It has to be batteries? Right?

But the weird thing is batteries still show 13+ volts even with nothing on?

This Damn thing is frustrating....

Wow, Teamaron; it sounds like you've got a completely different problem than what I had Hopefully consolidated minds of this forum can come up with a diagnosis...

On my old coach the generator and propane solenoid ran off the chasis batteries. If the chassis batteries are not great, when you alternator goes off you may not have enough voltage to fully open the propane solenoid for the generator. Then the generator may not have enough fuel to run at full power.

Agree. If battery power to the switch goes low then generator may shut down. Ca u check propane switch power?

Unless the inverter is off, wouldn't the generator bring the battery voltage up to the normal charge voltage and keep propane valve open?

Indirectly, there's a simple check. Light a burner on the stove. If it lights and goes right out, the solenoid is closed and you've just burned the residual LPG in the lines. Or maybe you've run out of propane in the tank. If the burner lights and stays lit, the solenoid is open.

However, on the Interstates, the propane solenoid is definitely powered from the house batteries, not the chassis battery. If you have enough battery power to start the generator, you've got enough for the propane solenoid to stay open. The only way you'd lose battery power while the generator is running is if your inverter/charger is malfunctioning (or switched off, as 73shark suggests) and not charging the house batteries— or maybe if you have an intermittent fault on a battery terminal connection so the inverter/charger can't charge the batteries.

I tried running burners and no problem there. But only when generator running. If jenny not on I don't even hear solenoid turn on or off at switch on outside of coach.

I think it's bad house batteries.

But how would you check for intermittent faults or inverter malfunction?
