Thank you Coyote Machine!
Will pass along to the fellas over at John Deere.
Coyote: I'm here in the fine state of North Carolina, the tractor is in the thriving metropolis know as Carthage.![]()
Is your fuel solenoid normally energized to run and deenergized to shut down?
Or energized to shut off the fuel?
On tractors requiring it to be energized to run there are normally two windings, a pull in which takes a higher current
and a maintain which holds it energized while working. This normal on many of the larger farm tractors.
Many of the smaller one seem to energize for a few seconds to shut down the fuel then drop out and let the fuel valve open.
These will normally have a small controller to operate them.
POST # 9, Page 1:Where are we now
The Fuel Shut-Off Solenoid is staying electrically charged (constantly on vice momentary on) once the tractor is started.
The electrical signal should be momentary to the Fuel Shut Off Solenoid, just long enough to retract the plunger and allow for fuel to flow.
However, with the constant charge there are are problems that result:
1 - The tractor will continue to run when the ignition (key) is switched to off
2 - The constant electrical charge heats up the wires until they melt.
3- The constant electrical charge and heat destroy the fuel shut off solenoid.
That statement doesn't make sense.
If it is momentary, it should be momentary to stop fuel flow,
then return to the run position.
