Doug hit it on the nose. All I need to know is how the circuit is run from the batteries . I don't have a schematic for the coach. I work on EST fire alarm panels and Bogen Intercoms for our schools here, If I know the trail I can repair the problem. RV's are totally different animals. The circuit and parts are key to repair the problem. Thank you Doug for the ideas on repair. It worked perfectly!
IF you have an Inverter/Charger, the heavy battery cable goes from the coach battery POS post to a 300 amp fuse and then to the Inverter/Charger. This has NOTHING to do with the Battery disconnect system. Then, they run another 12 volt wire(usually 4 or 6 gauge) from the coach battery to that disconnect solenoid. The other side of that solenoid then goes to the Fuse Block and other appliances that may have their own fuse. IF the battery disconnect fails or is turned OFF, the batteries still will charge from the Inverter/Charger and the 120 volt appliances that are Inverted from the Inverter will still come on, IF they do not require a 12 volt source to operate.
