The inverter converts 12v DC to 110v AC - Typically the inverter powers only a few items in most RVs - residential fridge if present, TVs are another common one... (Large diesel pushers power virtually everything...)
The inverter typically has an internal transfer switch - so if 110v power is available from either generator or shore power - it just passes it through... It only 'inverts' 12v to 110 when no 110 source is present.

So with generator on - the output of the inverter should be the 110v from the generator.

With the generator off/shore power disconnected, the output should still be 110v, but would be the result of inverting the 12v input.

I have an appointment with the RV dealership but it is 2 months out. I can fix this myself I just need to understand the concept. What is the best way to test the converter and the inverter with a volt meter. I believe the converter is the issue and not the inverter. As it he inverter does not charge the battery but the converter does with the generator on. Also with the inverter on everything works. What is the best way to test the converter. As stated earlier I can fix this myself I just. Need to know how.
