Hello, we just bought a 97 adventurer, it has solar panels and the panel controller seems to show charged but the only thing that works is the steps and the stereo/nav system in the dash. The fridge, guessing is 2 way shows no power as does the heater fan and roof vent. This is on DC only no shore power connected. Thinking there could be an issue with the isolator/inverter? Haven’t connected to shore power Yet since it’s still we haven’t moved it yet. We Haven’t tried the generator yet What kind of test can I do to isolate the problem? Thanks
