Massey Ferguson B.X.05 – Dash: Loader Mid Mount Electro Valve Solenoid Low Amp Draw

The tractor's onboard diagnostic system is detecting that the electrical current (amperage) flowing through the loader's mid-mount valve solenoid is lower than the expected threshold. This condition is typically caused by an open circuit, high resistance in the wiring harness/connectors, or a burned-out solenoid coil.

1. 1

   Ensure the tractor battery is fully charged (around 12.6V) and that system voltage is not collapsing under load

2. 2

   Inspect the wiring harness leading to the mid-mount valve block for corrosion, loose pins, or broken wires that would cause high electrical resistance

3. 3

   Disconnect the electrical plug from the suspect solenoid and measure the resistance (ohms) across the coil pins to check for an open circuit or unusually high resistance

4. 4

   Check for proper voltage reaching the connector when the loader joystick is activated (Trigger Test)

1. 1

   Relieve Pressure

   Turn off the tractor and cycle the loader joystick to relieve any residual hydraulic pressure.

2. 2

   Locate the Valve

   Locate the mid-mount electro-hydraulic valve block (usually mounted under the right side of the cab or near the loader subframe).

3. 3

   Disconnect

   Unplug the electrical connector from the faulty solenoid.

4. 4

   Remove Coil

   Remove the retaining nut at the end of the solenoid stem and slide the old coil off the hydraulic valve cartridge. (Note: Do not remove the hydraulic cartridge itself unless it is leaking or mechanically stuck, to avoid fluid loss).

5. 5

   Install New Coil

   Slide the replacement coil onto the stem, secure it with the retaining nut, and plug in the electrical connector.

6. 6

   Clear Codes

   Use a compatible Massey Ferguson diagnostic tool to clear the DTCs from the system and test the loader for proper operation.
