John Deere E203 – BaleTrak Pro: Twine Actuator Circuit Resistance Too High

The baler's control system has detected excessive electrical resistance in the power supply circuit for the twine actuator. This high resistance condition indicates a problem with the electrical current flowing to the actuator, which can prevent the twine wrapping cycle from functioning correctly.

1. 1

   Visually inspect the wiring harness leading to the twine actuator for chafed or pinched wires

2. 2

   Check all connectors in the actuator circuit to ensure they are clean, free of corrosion, and securely fastened

3. 3

   Examine the twine actuator for visible damage or signs of binding in the linkage

4. 4

   Enter Monitor-Controller Diagnostic Test Channel 018 (turn tractor key ON without starting engine, press and hold COUNTER key while turning monitor ON, hold COUNTER and press PLUS until 'CH018' appears, then release keys) to check static current (should be 0 to 1 amps)

5. 5

   Use the EXTEND and RETRACT keys to operate the actuator and check mid-stroke current using Channel 018 (should be 1 to 8 amps; lower indicates poor connections or low voltage, higher indicates binding or a failing motor)

6. 6

   Check stall current using Channel 018 (should be 22 to 30 amps; lower indicates bad connections, higher indicates a partially shorted motor or severe binding)

1. 1

   Repair wiring or connectors

   If harness damage or corrosion is found, repair or replace the affected wiring (typically Yellow 314A/314W and Green 315A/315W) and clean terminals thoroughly.

2. 2

   Replace the twine actuator

   If current readings indicate a faulty actuator (high mid-stroke or stall current), disconnect the electrical connector, remove mounting hardware, install the new actuator, and reconnect.

3. 3

   Clear the fault code

   Turn the monitor-controller on. With the actuator in its 'off' or home position, press the MINUS key to clear the E203 code.

4. 4

   Calibrate the new actuator

   Enter diagnostic mode Channel 029 (CH029). Fully retract and extend the actuator to record the new position values and ensure correct twine placement.

5. 5

   Perform final system test

   Run the actuator through its full range of motion using monitor controls and initiate a manual tying cycle to verify correct operation.
