I have a New Holland 675B tractor with a John Deere diesel engine in it.
The fuel shut-off solenoid had three wires in it, and due to vibration eventually ended up broken.
This happened to what I assume to be the wire that causes the solenoid to pull back first, as we could reach inside with a stick and manually open the valve, the solenoid would hold it open as long as the ignition switch was in the run position.
Eventually another wire broke loose out of the solenoid and the tractor wouldn't start period.
I replaced the solenoid with another solenoid from JD that has three wires as well however this solenoid has a white wire coming out of it with a terminal crimped on the end which would appear to go to ground.
However; we still have the exact same issue regardless of if this wire is grounded or not, the solenoid will not pull back on its own and open the fuel valve. It will stay in place if manually pushed back.
Does this white wire need to go to the starter side of the starter solenoid by chance? The red wire and black wire in the brown plug show +12v and ground as would be expected.
