Possible Causes
Debris or corrosion in Lectron connector latch, Deformed latch spring, Misalignment with vehicle inlet lock mechanism
How to Fix / Troubleshooting
Safety first: Ensure charging has stopped and the vehicle is unlocked before attempting to remove the connector.
- 1. Follow vehicle unlock procedure: Use the vehicle’s recommended method to release the charge port lock (key fob, in-car button, or app).
- 2. Inspect and clean latch: Once removed, examine the Lectron connector latch for dirt, rust, or damage. Clean with a dry brush and compressed air.
- 3. Lubricate lightly: Apply a very small amount of plastic-safe dry lubricant to the latch pivot if it feels sticky. Avoid oils that attract dust.
Resolution: If the latch remains stiff or fails to return fully, replace the Lectron J1772 handle/cable assembly to prevent future sticking or damage to the vehicle inlet.
