The other two going into the smoke unit.
I have three wires coming into the smoke unit, two are black one is red. One black one goes to the smoke on off switch. the other black comes from a pin on the motherboard and the red one comes from a pin on the motherboard.
if the brown wire passes through the smoke on/off switch, (assuming that is power to heat the element and run the fan,) what do the other two wires do?
My brown wire has about 7 V -assume that's the serial wire. My brown wire with a black stripe is showing no power coming out of it. I'm assuming at this point that my AC regulator is not workin as I do have power at the red wire going into it And I have continuity on both of the black wires to track common.
