Massey Ferguson 0B.01.11 – Mid Mount Valve Module: Loader Mid Mount Electro Valve Solenoid Low Amp Draw

Issue description

The control system is detecting less electrical current (amperage) than expected on the circuit that operates the mid-mount loader valve solenoid. A "low amp draw" typically points to high electrical resistance in the circuit, a loose or corroded connection, damaged wiring, or an internally failing (open) solenoid coil.

Check the cause

  1. Inspect the wiring harness between the Mid Mount Valve Module and the loader electro valve for any signs of damage, chafing, or breaks

  2. Inspect the electrical connector at the hydraulic valve for connection problems, loose pins, or corrosion

  3. Inspect the wiring for proper ground, continuity, and proper voltage

  4. Measure the resistance of the solenoid coil. If the coil shows an open circuit or unusually high resistance, the solenoid itself is the cause of the low amp draw

Repair steps

  1. Preparation

    Turn off the tractor and relieve hydraulic pressure from the loader circuit.

  2. Locate the Valve

    Locate the mid-mount electro valve block assembly on the tractor.

  3. Wiring Repair (If Applicable)

    If the diagnostic checks revealed faulty wiring, repair or replace the damaged sections of the wiring harness.

  4. Solenoid Replacement

    If the wiring is intact but the solenoid failed the resistance test, disconnect the electrical harness from the faulty solenoid.

  5. Remove Coil

    Remove the retaining nut/fastener holding the solenoid coil to the valve stem and slide the old coil off.

  6. Install Coil

    Install the new solenoid coil onto the valve and secure it.

  7. Reconnect Harness

    Reconnect the electrical harness.

  8. Clear Codes

    Use a compatible diagnostic tool or interface device to clear the DTCs from the system.

  9. Test

    Operate the loader to ensure normal function and verify that the fault code does not return.

Parts you might need

(2)
  • Genuine AGCO Solenoid Valve

    AG712817

    Always verify the part number stamped directly on the existing solenoid or valve block before ordering, as configurations vary between the 4700, 5600, and 7000 series tractors.

  • Walvoil Valve Assembly

    25H49770

    Always verify the part number stamped directly on the existing solenoid or valve block before ordering, as configurations vary between the 4700, 5600, and 7000 series tractors.
