Possible Causes

Dirty or worn J1772 pins, Misalignment of connector in vehicle inlet, Weak pilot signal amplitude, Vehicle firmware incompatibility with older EVSE firmware

How to Fix / Troubleshooting

Safety first: Do not force the connector into the vehicle inlet. Turn OFF the breaker before opening the EVSE.

  • Clean connector: Wipe the J1772 pins with a clean, dry, lint-free cloth. Do not use lubricants or sprays.
  • Firm insertion: Insert the connector fully until the latch clicks. Partial insertion can prevent proper pilot and proximity contact.
  • Test another EVSE: Charge the vehicle at a public station to confirm the vehicle is operating normally.
  • Firmware check: Contact ClipperCreek support with your model and serial number to determine if a control board firmware update is recommended for your vehicle model.

If multiple vehicles fail to charge on this EVSE while working elsewhere, the control board or cable assembly likely requires replacement.
