Possible Causes

Pilot signal not recognized by vehicle, Faulty J1772 connector, Loose low-voltage harness between cable and main board

How to Fix / Troubleshooting

Safety first: Turn OFF the breaker before opening the unit or handling internal wiring.

  • 1. Try another vehicle: If possible, connect a different EV to determine whether the issue is with the Lectron charger or the vehicle.
  • 2. Inspect the J1772 connector: Check for bent pins, corrosion, or debris. Clean with electrical contact cleaner and a soft brush.
  • 3. Check cable strain relief: Ensure the cable gland at the Lectron housing is tight and that the cable has not been pulled out or twisted excessively.
  • 4. Internal harness check: With power OFF, open the unit and verify that the low-voltage harness from the cable to the main control board is fully seated and undamaged.

Resolution: If the connector and harness are intact and the issue occurs with multiple vehicles, the pilot circuit on the main control board or the cable assembly may be defective. Replace the Lectron J1772 cable assembly first; if the problem persists, replace the main control board.
