Jim:

Not sure what your issue is from that description. Is the roof air not running? Not cooling but fan running? What elec. panel are you referring to, is that the thermostat?

If the genset is running and the main engine is providing 12V to the coach via the alternator, it may be causing the inverter/charger to go into fault mode. Send me a PM and I might be able to help. Further information would be nice as requested by EM above as well.

On the Hart interface panel on the left under battery status it shows the AC in fault with the engin and gen set running and the roof air on.

That may be it's state in that genset mode. Someone with this configuration needs to confirm this. Mine has the xantrex and Onan Genset Configuration, and I get the ac fault when genset is running too.

Thanks for the info. I guess if yours also get the AC fault light, maybe thats the way it's to be. EngineerMike, is that the way you see it ????????

I guess, if all the stuff is running OK- ignore the warning and keep on trucking.

The one thing I have yet to see recommended in this thread is RTFM.

What does the MANUAL say about that light that is lit?

Normally I'd download the manual but I'm a bit overloading the bandwidth already today.

In reading this I believe that you are taking about the panel for inverter, If so I had a similar problem and it was traced to the regulator for the solar panels. The regulator was allowing the batteries to over charge, once replaced it solved the problems, or it could be the Battery Isolator allowing the batteries to over charge.

We have had a similar problem. I turn off the inverter/charger when we travel with the genset on. We don't get the light then.

I didn't know there was a fix for that.

I'll have to get with Dave.

Good thing we have these wizards to lean on!!

We live out in our old van. Travel all across this land. Drive until the city lights dissolve into a country sky, me and you - hand in hand.

RTFM? Really?
My dad taught me that was un-manly. Then he showed me his hardware breaking act.

We also turn of the inverter/charger. I just figured that it was because both the alternator and the generator were trying to charge the batteries and there was a conflict. Easiest solution was to turn off the charge function.

FWIW - Our coach has two solar panels. One is the 100W and the other was 10W panel. The 10W was glued directly to the roof, and over the first season, it got so hot up there it fried some of the cells. It caused the battery charger to constantly keep the batteries charged, partially boiling off the electrolyte. I mentioned this once I realized it and Dale Gerstel said that the solar panel was causing this. Since there was no warranty on the little one, I just cut and taped off the leads so it could not cause this problem. It was not regulated as far as I could tell, but it might have been. The regulator is under our bathroom sink and it seems to work fine and so I don’t pay much attention to it unless it should have a charge indication and it dosent, then I wonder why. Maybe it got fried as well, but don’t think so as the manual shows what it is supposed to do and it seems to be doing it.
