Massey Ferguson 8.02.62 – HITCH (Rear Hitch Module): Rear Linkage Raise Solenoid High Amp Draw (HITCH)

This code indicates that the electrical circuit controlling the solenoid valve responsible for raising the rear 3-point hitch is drawing more electrical current (amperage) than the controller expects. This condition typically points to a short circuit to ground in the wiring harness, a shorted internal solenoid coil, or water ingress bridging the electrical connections.

1. 1

   Visually inspect the wiring harness running from the Rear Hitch Module to the rear linkage raise solenoid for chafed insulation, pinched wires, or melted spots shorting to ground

2. 2

   Disconnect the plug at the raise solenoid and check for water ingress, mud, or severe corrosion across the pins

3. 3

   Perform a coil resistance test using a multimeter across the pins of the raise solenoid coil (a reading near 0 ohms indicates a shorted internal coil)

4. 4

   Perform a harness continuity test with the solenoid and Hitch Module disconnected by testing the power wire for continuity to ground

1. 1

   Safety First

   Ensure the tractor is turned off, the key is removed, and the rear 3-point hitch is fully lowered to the ground to relieve all hydraulic pressure in the lift circuit.

2. 2

   Access the Valve Block

   Locate the rear hitch hydraulic control valve block (typically mounted on or near the rear lift cover). Identify the specific 'Raise' solenoid.

3. 3

   Wiring Repair (If Applicable)

   If the diagnostic checks revealed a short in the harness, splice and heat-shrink the damaged wire, or replace the affected harness section.

4. 4

   Solenoid Replacement (If Applicable)

   Disconnect the electrical connector from the raise solenoid. Remove the retaining nut or bolt holding the solenoid coil to the valve stem. Slide the old solenoid coil off the cartridge. (Note: If the valve cartridge itself is sticking or damaged, you may need to unthread the entire cartridge valve from the block. Have a catch pan ready for hydraulic fluid). Slide the new solenoid coil onto the stem and secure it with the retaining nut. Reconnect the electrical harness.

5. 5

   Clear Codes & Test

   Use a compatible diagnostic tool to clear the 8.02.62 fault code from the Hitch Module. Start the tractor and cycle the rear linkage raise/lower switches to verify smooth operation and ensure the code does not return.
