    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    Thanks for all the input, I have to head back to work and won’t be able to trace wires and draw diagram until the weekend. Also, I’m assuming the diodes are damaged since the voltage is so messed up. I’ll try to test that. Thanks again!

    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    Pretty sure the solenoids aren’t doing what they are supposed to do because one side is getting 12v across both terminals, while the opposing side is gets 12v on one terminal with the F pushed, and nothing with R pushed.

    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    As far and rewiring, I was planning on running the 12v line from the starter switch to feed both F/R switches, then run Connect each F/R switch to + terminal on each respective solenoid. Then ground the - terminals of the solenoid, and if needed, install the TVS in line diodes to prevent voltage...

    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    Ok, so I checked the relays. When the key is on, both relays have 12v to terminals 1, 7, 10, and 11. When the F or R pedal is pushed, #4 gets power respectively. Problem is, the F pedal activates one solenoid and then both terminals on the right solenoid and the lower terminal on the left...

    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    Yeah, now that I know this isn't original wiring and relays, I may try that. But, it worked fine before it didn't. So I will try and check the leads, and maybe replace the relays at $10 a piece to see if it is the easy route. If that doesn't work, then rewiring is the plan. So, if I rewire...

    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    This is the diagram the manual shows. It’s a 30+ year old tractor. Has anyone out there seen these relays behind the dash? Mine were enclosed in a 4x4 electrical box next to the ignition switch. The wiring sure looks original...or at least well done and old, lol

    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    Here is the stock plug to the solenoid, there are two, one one each side, wire apear stock. Voltage at the plugs terminal connectors are all varied around 4 +\- volts each. https://www.dropbox.com/s/dr37j6cqklu6uuu/Photo%20Dec%2017%2C%2017%2024%2049%20%281%29.jpg?dl=0 Here is the solenoid unit...

    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    No, not yet. But I’m hoping someone will see this that has a clue. I think there is some kind of electrical backfeed in the relays behind the dash that seem to click when the pedals are pushed, or maybe the inline diodes are bad, but can’t find where they are. Frustrating for sure, don’t want to...

    Help: Electrical question on a Massey Ferguson 50e - Shuttleshift Solenoid

    I have a Massey Ferguson 50e tractor loader that will not engage in forward or reverse. I have replaced the Vickers solenoid block, and no luck. Fluids are up to correct levels, etc. The pedals cause the relays on the steering column to click, but no solenoid action. I tested current at the...
