Possible Causes

Dirty or oxidized pins on J1772 connector, Weak pilot signal amplitude, Sticking proximity switch in handle, Loose cable harness connection on control board

How to Fix / Troubleshooting

Safety: Turn OFF power before opening the unit. Do not insert tools into the vehicle inlet or connector.

  • 1. Try another vehicle:
    • If another EV charges normally, the issue may be with the original vehicle.
  • 2. Inspect and clean connector:
    • Examine the J1772 pins for dirt or oxidation.
    • Clean gently with a dry, lint-free cloth.
  • 3. Check handle operation:
    • Ensure the trigger/latch moves freely and is not stuck partially engaged.
  • 4. Internal cable check:
    • With power OFF, open the charger and verify the cable harness is fully seated on the control board.
  • 5. Replace cable assembly: If intermittent operation persists and the handle or cable shows wear, replace the AMPROAD J1772 cable & handle assembly.
