Massey Ferguson B.X.08 – Mid Mount Valve Module: Loader Mid Mount Electro Valve Solenoid Low Amp Draw

The control module is detecting less electrical current (amperage) than expected flowing through the solenoid circuit that controls the mid-mount loader valve. A 'low amp draw' typically points to high electrical resistance, a loose or corroded connection, damaged wiring, or a failing/open solenoid coil.

1. 1

   Visual Inspection: Locate the mid-mount valve block (typically where the loader hydraulic lines tie into the tractor chassis). Inspect the wiring harness leading to the electro-hydraulic solenoids for chafing, breaks, or pinch points.

2. 2

   Connector Check: Disconnect the wiring harness at the affected solenoid. Check for water ingress, dirt, or corroded pins. Ensure the pins are tight and making good contact.

3. 3

   Resistance Test (Ohms): Using a multimeter, measure the resistance across the two pins of the solenoid coil. An infinite reading (OL) indicates an internal break (open circuit) in the coil, confirming the coil is dead.

4. 4

   Voltage/Command Test: With the key on, probe the harness side of the connector while commanding the loader joystick. You should see a voltage signal sent to the valve. If no voltage is present, the issue lies in the wiring harness or the Mid Mount Valve Module rather than the solenoid itself.

1. 1

   Safety First

   Lower the loader to the ground to relieve hydraulic pressure. Turn off the tractor and disconnect the negative battery cable.

2. 2

   Locate the Valve

   Access the mid-mount electro valve block. Clean the area around the valve to prevent dirt from entering the hydraulic system.

3. 3

   Disconnect Wiring

   Unplug the electrical connector from the faulty solenoid.

4. 4

   Remove the Solenoid Coil

   Remove the retaining nut or cap screw at the end of the valve stem that holds the solenoid coil in place.

5. 5

   Swap the Coil

   Slide the old solenoid coil off the valve cartridge tube. (Note: You usually do not need to remove the hydraulic cartridge itself, meaning no hydraulic fluid will be lost).

6. 6

   Install New Part

   Slide the new solenoid coil onto the stem and secure it with the retaining nut. Do not overtighten, as this can crack the plastic coil housing.

7. 7

   Reconnect

   Plug the electrical connector back in, ensuring it clicks and locks securely.

8. 8

   Clear Codes & Test

   Reconnect the battery. Use a compatible diagnostic tool or the tractor's dash interface to clear the 0B.X.08 fault code. Start the tractor and test the loader joystick to ensure proper operation.
