Possible Causes

Faulty pilot signal stability on main board, Loose control wiring to contactor, Interference from unstable grid voltage

How to Fix / Troubleshooting

Safety first: Repeated cycling stresses components. Turn OFF the breaker before inspection.

  • 1. Test with another EV: Determine if the behavior is vehicle-specific.
  • 2. Check supply voltage stability: Have an electrician measure voltage during cycling. Large fluctuations may indicate a supply issue.
  • 3. Inspect control wiring: With power OFF, open the unit and ensure all low-voltage control wires between the main board and contactor are secure.

Resolution: If supply is stable and wiring is secure, the main control board may be misdriving the contactor. Replace the Lectron main control board.
