JD455 PTO

[DeereBris]

Hello, I have an old JD 455 and the mid pto does not spin. I have installed a new PTO solenoid and nothing. I ran a mid PTO pressure test as per the manual and I received a 0 psi reading. I also did a pump test and the reading was ok. Does anyone have any ideas how I may diagnose this problem, it sounds very much like an electrical problem to me.

My 425 had same problem. Cause was a faulty ignition switch module. There is a relay on the circuit board that controls the PTO function.
