Class "C" used !
House Hold batteries (New) not keeping charge from one day to another.
 
Are you plugged into 120VAC?
Do you have a volt meter?
Do you know how to use it?
Are you plugged into shore power all the time?

  • And, if you're not plugged in all the time, how long were you plugged in prior to unplugging?
  • Exactly what was your power usage, in detail, while you were unplugged (how many lights, how long? TV? Inverter? Fans(s). Basement lights left on?)
 
    As implied by the foregoing posts, you may well have something left on, or even a direct short.  A new fully charged battery should last a few days with normal usage unless you have a major draw.  However, without all the details, we are quessing blind.

Welcome to the RV Forum derbysr

Without more information it would be hard to offer much information. I would start with making sure the converter is working. Otherwise the battery won't charge when plugged into 120 volts
 
Ahhh only had Generator power on and voltage on batteries was 11.6 when i  shut down  Generator.
Today jump started Household Batteries  and plug into shore power @ 10 AM.
Batteries up to 12.8  @W 1:00 PM .  8)
 
You will have to trace some wires, but I suspect the generator does not charge the house battery.
 
      Just to make sure, you have to disconnect from shore (110) power to test the battery, in fact many suggest that you unhook the ground prior to testing.

The generator "should" charge the house batteries. BUT it does so indirectly by powering the CONverter which actually does the job, the same way it does it when plugged in to 120V. If plugging in does result in charging as desired, then wire chasing may be in order. A Battery under charge should read 13.5-14.5 Volts, the extra voltage boost coming from the charger itself. A fully charged battery alone should read about 12.6V or so.

The Chassis (starter) battery is probably not charged unless the engine is running but that can be remedied by adding a unit like the Trk-L-Start to maintain its charge while plugged in. Running the engine should also charge the house batteries.

Remember, charging batteries is not a 5 minute affair, it takes many hours to charge them properly.

Years, makes and models of the Class C, the converter and/or main power panel would really help in diagnosis.
 
File for testing Inverter to large to post here according to instructions !
