Usually Brambles, the fridge/freezer is wired via a relay and only works on 12 v when the engine is running.It is up to the convertor which way he wires up the Fridge/Freezer. Some are connected to the service battery for the ignition, but mine for example uses thr liesure battery. The main 12 volts supply for Fridge or Freezer comes from the fuse marked * and would not be used for the ignition circuit.
:Cool: My Newmar (RV) MAY soon be running on 12 volt power driving a 110 volt Inverter and re-charged by Solar power.I have got one of these newish super dooper full size ff that selects the most efficient power sourse at any given time.
Or that is what the book says!
