Conversely, when the switch is “off,” it completely disconnects the house batteries, preventing drain and protecting sensitive electronics.
This is especially important for extended storage periods to prevent battery damage from parasitic drain.
Power Flow Diagram
Imagine a simple diagram. At the top, we have your RV’s house batteries (Battery 1 and Battery 2, if you have a dual-battery setup). From the batteries, a thick line represents the main positive (+) cable leading to the battery switch. The switch itself is depicted as a simple on/off toggle. From the switch’s output, another thick line represents the main positive cable that branches out to various fuse panels or circuit breakers.
These fuse panels then distribute power to individual systems: lights, water pump, refrigerator, air conditioner, and so on. Each branch line has a smaller fuse or breaker to protect that specific circuit. Finally, each appliance or system (lights, pump, etc.) is shown connected to its own branch. Each wire has a corresponding negative (-) return path, completing the circuit, but for simplicity, these negative return paths are not explicitly shown in this simplified representation.
The diagram visually clarifies how the battery switch controls the flow of power to all connected systems.
