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

[Norman Martin]

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?

Thanks,

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?
