Hi JIM Q,
It would help us to know the details of the coach you own. Year, make, model, inverter, charger, etc.
Basically, take a VDC reading from the charger connections to the house battery(s). It should read 13.5 VDC or higher. Take a VDC reading on the house battery(s). It should be the same as the reading from the charger. If so, the coach battery(s) are being charged. If not, the charger or a component between the charger and the coach battery(s) is suspect. The coach battery could also be bad.
The chassis battery may or may not be charged from the charger. It all depends on how the coach is wired.
