Low Power Propane Switch - March 2024 ($55)

After doing some internet searching, I found that Leonard Casella in Pennsylvania sells a modified low power switch.  I contacted him and he sent me one for $55. The install was fairly easy, it uses the same wires but needs to have a ground wire which I tapped off the compartment light. 

The switch consists of a three way toggle with a BUCK converter that lowers the current draw to keep the solenoid open. The LED is for testing purposes, I did not use it. 

This is the original Propane switch

This is the new one installed. There is not a good place for the BUCK converter in the Serenity, so I stuck it to the utility compartment wall. I tapped the ground off the compartment light. 

I turned on the propane stove to ensure the valve was open in the On and PS positions. 

It reduces the power draw by 0.83A and only consumes 0.15A while keeping the gas solenoid open. 

This is the battery monitor with the switch in the On position.

This is the monitor with the switch in the PS position. 

This is the monitor in the off position.

I consider this a success and still can't understand why an RV manufacturer would put such a device in a rig with limited battery capacity.
