0B.00.05

Massey Ferguson 0B.00.05 – Mid Mount Valve Module: Loader Mid Mount Electro Valve Solenoid Low Amp Draw

Issue description

The control module is detecting that the electrical current (amperage) flowing through the solenoid coil on the mid-mount loader valve is lower than the expected threshold. A "low amp draw" condition almost always points to high electrical resistance, an open circuit, a broken wire, a disconnected plug, or a burnt-out (open) solenoid coil winding.

Check the cause

  1. Inspect the wiring harness running from the Mid Mount Valve Module to the loader valve block for chafed wires, pinched lines, or rodent damage.

  2. Disconnect the electrical plug at the affected mid-mount valve solenoid and check for water intrusion, corrosion, or pushed-back pins.

  3. Perform a coil resistance test using a digital multimeter across the two pins of the solenoid coil; a reading of 'OL' or infinite resistance indicates a broken internal winding.

  4. Perform a voltage supply test by unplugging the connector and having an operator actuate the loader joystick to ensure the module is sending the command signal.

Repair steps

  1. Safety First

    Lower the loader to the ground, turn off the tractor, and cycle the loader joystick to relieve any residual hydraulic pressure in the system. Disconnect the negative battery terminal.

  2. Locate the Valve

    Locate the mid-mount electro-hydraulic valve block on the chassis.

  3. Disconnect

    Unplug the electrical connector from the faulty solenoid.

  4. Remove the Coil

    Remove the retaining nut or cap screw located at the top/end of the valve stem.

  5. Slide Off

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

  6. Install New Coil

    Clean the valve stem of any dirt or debris. Slide the new solenoid coil over the stem.

  7. Secure

    Reinstall and tighten the retaining nut to the manufacturer's torque spec (do not overtighten, as this can crack the plastic coil housing).

  8. Reconnect

    Plug the electrical connector back into the new solenoid.

  9. Test

    Reconnect the battery, start the tractor, and operate the loader joystick to verify smooth operation and ensure the 0B.00.05 code has cleared.

Parts you might need

(1)
  • Loader Mid Mount Electro Valve Solenoid Coil

    The exact AGCO part number depends heavily on the specific brand of the mid-mount valve block installed on your tractor at the factory (e.g., Bosch Rexroth, Husco). You must consult the AGCO/Massey Ferguson parts catalog using your tractor's specific VIN/Serial Number to get the correct coil. Ensure you are buying just the electrical coil (magnet) if the hydraulic valve itself is not leaking or sticking mechanically.
