Massey Ferguson M08 – Mid Mount Valve Module: Loader Mid Mount Electro Valve Solenoid Low Amp Draw

The control module is detecting less electrical current than expected flowing through the loader's electro-hydraulic solenoid circuit when the valve is commanded to open. A "low amp draw" typically points to high electrical resistance in the circuit, a broken/chafed wire, a heavily corroded connector, or a burned-out (open) solenoid coil.

1. 1

   Visual Wiring Inspection: Trace the wiring harness from the Mid Mount Valve Module to the loader electro-valve block. Look for chafing, cuts, or pinched wires, especially where the harness routes near moving loader linkages or hot engine components.

2. 2

   Connector Check: Disconnect the electrical connector at the affected solenoid. Inspect for water ingress, bent pins, or green corrosion, which can cause high resistance and trigger a low amp draw code.

3. 3

   Coil Resistance Test: Use a digital multimeter to measure the resistance (Ohms) across the two pins of the solenoid coil. A reading of infinite resistance (OL) indicates an open/burned-out coil that must be replaced. You can compare this reading to a known-good solenoid on an adjacent valve spool.

4. 4

   Voltage Supply Test: With the key ON (engine off), have a helper actuate the loader joystick while you check for proper voltage and ground at the harness connector to rule out a module or wiring failure.

1. 1

   Turn off the tractor, remove the key, and disconnect the negative battery cable for safety.

   Turn off the tractor, remove the key, and disconnect the negative battery cable for safety.

2. 2

   Relieve any residual hydraulic pressure by moving the loader joystick in all directions.

3. 3

   Locate the mid-mount electro-hydraulic valve block.

   Locate the mid-mount electro-hydraulic valve block (typically mounted under the right-hand side of the cab or along the right frame rail).

4. 4

   Disconnect the wiring harness connector from the faulty solenoid.

   Disconnect the wiring harness connector from the faulty solenoid.

5. 5

   Remove the retaining nut or cap holding the solenoid coil onto the hydraulic valve cartridge stem.

   Remove the retaining nut or cap holding the solenoid coil onto the hydraulic valve cartridge stem.

6. 6

   Slide the faulty solenoid coil off the stem.

   Slide the faulty solenoid coil off the stem. (Note: You generally do not need to open the hydraulic system or remove the valve cartridge itself to replace the coil, preventing fluid loss).

7. 7

   Clean the valve stem of any dirt or debris, and slide the new solenoid coil into place.

   Clean the valve stem of any dirt or debris, and slide the new solenoid coil into place.

8. 8

   Install and tighten the retaining nut to the manufacturer's torque specification.

   Install and tighten the retaining nut to the manufacturer's torque specification.

9. 9

   Reconnect the electrical connector.

   Reconnect the electrical connector, ensuring the weather-pack seal clicks and locks securely.

10. 10

    Reconnect the battery, start the tractor, and clear the fault codes.

    Reconnect the battery, start the tractor, and clear the fault codes using the dash interface or an AGCO EDT (Electronic Diagnostic Tool). Test the loader functions for proper operation.
