Use/Store switch-- Really a house battery disconnect switch. It disconnects only the house battery from providing 12 volts to the house. Does not affect the 120 volt system. ( Some 12 volt detectors may still be powered by the battery)
If you are connected to the power pedestal or your generator and getting 120 volts, all your 12 volt circuits may get power from your converter even with the use/store switch off. But if you unplug from the pedestal you would lose your 12 volt lights, fans etc.
Some 120 volt appliances also need 12 volts for control circuits, (refrigerators) 120 volt circuits are normally protected by circuit breakers and 12 volt by fuses.
The resistor- Reading the ohms of a resistor in a circuit you are also reading the resistance of anything in parallel with the resistor.
Most absorption refrigerators (RV) take a full day to cool down when first turned on..
