So with a major coolant leak into the oil most likely a head gasket on my 86 4x4 project I stole the instrument cluster and tach sensor out of it for my 86 2wd instead of waiting for the snow to melt to get to the junk yards and grab them. Since the 4x4 has some major wiring issues I was hoping that was the reason it was jumpy and wouldn't read a steady rpm, so I installed it into the 2wd and it's performing the same. I checked the wiring on my truck and the problem isn't the wires from the cluster to the quick connect for the tach sensor. So is there a way to test the sensor its self? A lot of sensors in the new diesels in construction equipment I fix for a living have a tolerable ohm range for most sensors can these be tested the same way?
