Possible Causes

Unstable pilot signal, Low supply voltage causing coil dropout, Faulty contactor coil, Control board repeatedly aborting due to detected fault

How to Fix / Troubleshooting

Safety first: Repeated contactor operation can cause wear and heat.

  • Step 1 – Stop attempts: Unplug the vehicle and turn the breaker OFF for 5 minutes to allow the unit to reset.
  • Step 2 – Check supply voltage: Have a qualified person verify that line voltage remains stable when the charger attempts to start.
  • Step 3 – Inspect contactor: With power OFF and cover removed, check the contactor for signs of overheating or mechanical damage.

If chatter resumes when trying to charge, the contactor or control logic is likely faulty and should be serviced.
