Re: Mental Gymnastics
White box is a propane sensor. 98% sure.
The switch is on or off. Follow the wires, one will come from power, one will go to something. That something goes on or off...
edit: yup, the propane detector as larrie said. 3 red wires at the two items, only one coming from the loom...
green light should go on or off, if not check power at switch terminal (the red wire from the loom should be 12v+)
