The thermostats seem to be OK. On both the front and rear units, pin 1 shows 13 volts when on low, nothing on pin 2, and the reverse when set to high. Interestingly, pins 5 and 6 both show 13 volts on both low and high. I guess the fans do the switching of current to the compressors. Today I will test for volts going to the compressors while running on high and low as configured by the factory and with the compressor leads switched.
