With ignition turned on, but engine not started, if one lead reads 12 v and the other does not, then there is an open circuit in the clutch coil.
Another simple way to test is with the engine running, touch a wire connected to ground to the black/pink wire of the connector, the clutch should engage.
Thiis "Hotwire" should void any other system check that is not allowing boost, would that be correct?
With the key in the on position one has 12 volts and the other has little voltage so you say the clutch coil is bad? Do I read that correctly? How could I have done the first check where I got 12 volts on one and little on the other without the key in the on position, if key is not on there isn't power to either wire. I am confused.
With no key involved I get no voltage at either pin. With the key on I get 12v on one and little on the other, that is bad? Are you saying with the key on both pins should show 12volts?
I hope you misworded that! I was getting my hopes up!
