House Battery's Charged But won't run inside of coach

[Norman Martin]

I disconnected the battery cables and tested the house batteries and they are fully charged. They were new 2 years ago. If I am not plugged in or running the generator I don't have power inside the coach. Does anyone have an idea where to look for problem?

12 volt power, 110 Volt Power, 240 volt power, Which power are you talking about?

Norman,

Piggy-backing off Mike the question is which power....if the batteries are good you should have the 12v power at a minimum but for the 110+ power that would come via the inverters. So if you don't have 110+ you have an inverter issue and in turn if you have neither 12v or 110+ then you probably have an equalizer/converter issue also with the vdc conversion to the 12v side of the house batteries.

Thanks Mike and Jerry for the response. I'll get with the Magnum tech people and see if they can help me.

After learning a little bit about inverters, one of them doesn't output 120V to the coach. I removed it and took it for repair. Thanks to everyone that responded to my problem.

Great to hear Norman....sounds like that was the problem.

I took the inverter that had no output to National RV for repair. They checked it and found no problem. I installed it and we have output now. Not sure what the issue was but both inverters working now. Batteries show full charge after being plugged in all night.
It seems I have another problem, my dash shows 13.6 charge from 12-V alternator but when I checked the large post it only showed 12.2. Not sure where to go from here. Any suggestions?

Wow Norman, that's strange on the inverter....now one possibility is there was a loose connection and of course once you took the inverter out and re-installed that fixed that issue....Just looking at reasons for failed output. Now with the voltage display are you talking about the amperage while the engine is running or are you talking about current standard idle voltage display? Also do you have a digital display?
