Looking for wiring diagram for this dryer. Also wondering if you could explain how dryer motor is energized. I have power (120vac) at terminals 1 (which is a red wire going through power relay) 2 (which is a black wire coming directly from incoming power) 5 (which is a white wire going through a switch on the back of the dryer motor it has 120vac power on it depending on the switch) and 4 which is a brown wire which does not appear to have any voltage on it.

Thanks,
John Penny
