Possible Causes
One phase missing at charger input, Loose or burned phase conductor at terminal block, Blown upstream fuse on one phase, Faulty phase monitoring circuit on control board
How to Fix / Troubleshooting
Safety warning: Three-phase systems are hazardous. Only qualified persons should work on them. Always isolate power before opening the charger.
- 1. Visual inspection: With power OFF, open the charger and inspect the three-phase input terminals (L1, L2, L3). Look for loose screws, discoloration, or melted insulation.
- 2. Tighten terminals: Retighten all phase terminals to the specified torque if any are loose.
- 3. Check upstream protection: Inspect the three-phase breaker or fuses feeding the charger. Replace any blown fuses and investigate the cause.
- 4. Measure phase voltages (qualified only): With power ON, measure voltage between each phase and neutral/earth. All phases should be within the specified range and reasonably balanced.
- 5. Power-cycle and test: After correcting any wiring or fuse issues, power-cycle the charger and attempt a new session.
- 6. If E14 persists with correct voltages: The phase monitoring circuit on the Land Rover control board may be defective and require replacement.
