Overheating at internal terminals causing thermal cutback, Loose main contactor coil connection, Marginal RCD/RCM module tripping and auto-resetting, Supply voltage sag under load
How to Fix / Troubleshooting
Safety warning: Repeated interruptions may indicate overheating or wiring issues. Isolate power before inspection.
- 1. Observe LEDs/app: Watch the charger LEDs or app when the interruption occurs. Note any brief fault indications.
- 2. Check for heat: After an interruption, carefully feel the charger enclosure and cable. If very warm, reduce the charging current in the app and improve ventilation.
- 3. Inspect internal terminals: With power OFF, open the charger and check all input and output terminals for looseness or discoloration. Retighten to specified torque.
- 4. Monitor supply voltage (qualified only): Measure voltage at the charger during charging to see if it drops significantly, indicating a supply issue.
- 5. Test with another circuit (if portable unit): If using a Land Rover portable home charger, try a different dedicated outlet with correct rating.
- 6. If issue persists: Have a technician test the contactor, RCD/RCM, and control board for intermittent faults and replace as needed.
