Condensing motor test
The condenser motor gets 13 VDC from J2 connector on the motherboard. Measure between pin 8 and 5 You also should get this voltage at the motor connector between the red and yellow wires.
Pin 3 wire to pin 8 motor connector wires red and white is an optional winding, should be 13 volts
Both windings should measure about 1.7 Kohm.
The evaporator motor wiring
J2 pin 8 red wire to pin 3 white J2 pin 3 12 volts, around 1.7 kohm
J2 pin 4 yelow wire to pin 1 blue wire 6.3 volt square wave also 1.7kohm
