Hi folks,
I just installed four new CG-2 batteries in my 5th wheel. Model is named in my signature. Most of the 12 volt things in my coach do not work on battery power. I've checked the voltage with a load tester. It is and remains very strong. I've checked circuit breakers.
These things work on battery power:
1. generator cranks and starts.
2. electro-hydraulic slides operate normally
3. electro-hydraulic landing gear operates normally
4. entire 12 volt system works on generator power.
5. entire 12 volt system works on shoreline power.
These things do not work on battery power:
1. coach 12 volt lights.
2. refrigerator power inverter. (residential 110 volt only fridge.) this inverter is solely dedicated to powering the fridge.
3. water pump.
I'm assuming the transfer switch has nothing to do with this???
So . . . what could possibly have happened here??? Thanks for any help you can give!
