When I measure the voltage with a DVM the yellow wire at the ICM I get 6v with VR unplugged and 10v with the VR plugged in but when measure with the DVA I get 0v unplugged and 10v plugged in. The G/W goes to ground like it suppose to. I tested the VR's an both tested the same, red to yellow, open circuit and 0.5v the order way for all three yellows. The ICM gets it 12v through the red wire has it should. We know the signal from the pulser(Bu/Y) is good and I verified that the ICM is getting the signal, I get 4.6v Peak at the ICM.
