If you are running the generator and charging the house batteries and IF the house batteries and the engine batteries are electrically tied then the ammeter will show up h engine batteries to appear to be discharging. This happens because the alternator regulator is set around 13.7 volts and most battery chargers run around 14 v in the bulk mode.
I don't see how that can be all of a sudden. We have had this rig since 1008 and the Trimetric monitor for the last three and have not seen this until this spring.
As I mentioned in my first post I have a Xantrex Echo Charger. It charges the chassis batteries from the house batteries if needed AND the chassis batteries are at 13.V or higher.
AND it's mot just meter reading. When I first noticed this I left the house with the chassis batteries reading 12.2V, half way to the shop the battery warning light came on and I arrived at the shop with 11.8 volts at the chassis battery. The tech said the alternator chechked out. He has been away on holidays, just waiting to get back in.
