John Deere 000737.06 – PTQ: Clutch 1 Solenoid High Amps

The PTQ controller has detected excessively high electrical current (amperage) in the circuit for the K2 speed control solenoid valve (Direct Drive Clutch 1). This condition typically indicates an electrical short circuit within the solenoid coil itself or in the wiring harness connecting the solenoid to the control module, which can disrupt transmission shifting and clutch control.

1. 1

   Visually inspect the wiring harness leading to the transmission speed control solenoids for chafed or melted insulation, pinched wires, or corrosion.

2. 2

   Disconnect the K2 solenoid and measure resistance between its two pins; a reading close to zero or significantly lower than spec indicates an internal short.

3. 3

   Measure resistance from each pin of the K2 solenoid to the tractor's chassis ground; any continuity indicates an internal short to ground.

4. 4

   Inspect the tractor-side wiring harness connector and measure resistance between the power supply wire and a known good ground to check for external shorts to the chassis.

5. 5

   Locate the speed control solenoids on the side of the transmission housing; note that a protective cover or skid plate may need to be removed for access.

1. 1

   Park Safely

   Park the tractor on a level surface, engage the park brake, and turn off the engine.

2. 2

   Disconnect Power

   Disconnect the battery before beginning any electrical repairs to prevent accidental shorts.

3. 3

   Locate and Access the Solenoid

   Locate the faulty K2 speed control solenoid on the transmission. Have a catch pan ready, as draining a small amount of transmission oil may be required.

4. 4

   Test the Solenoid

   Perform the resistance tests to confirm the solenoid is faulty. Check for hydraulic oil seeping through the solenoid and contaminating the electrical connector, which is a common cause for a short.

5. 5

   Replace the Solenoid

   Unplug the electrical connector and carefully unscrew the solenoid from the transmission valve body. Ensure the new solenoid's O-rings are clean and properly lubricated with hydraulic fluid, screw it into the valve body, torque to the manufacturer's specification, and reconnect the electrical connector securely.

6. 6

   Repair Wiring (If Necessary)

   If the diagnostic checks indicated a short in the wiring harness, locate the damaged section and repair it using appropriate sealed connectors and heat shrink tubing to protect against moisture and vibration.

7. 7

   Final Checks

   Reconnect the battery, top off the transmission fluid, start the tractor, and check for leaks around the newly installed solenoid. Operate the transmission to ensure proper shifting, perform a transmission calibration procedure if necessary, and clear the fault codes.
