Possible Causes
Short circuit or partial short in cable, Faulty current transformer (CT) sensor, Loose CT harness, Miscalibrated current sensing on control board
How to Fix / Troubleshooting
Safety warning: Overcurrent conditions can cause overheating. If the cable feels hot, stop using the charger immediately.
- Inspect cable and connector: Look for visible damage, melted plastic, or discoloration at the plug or cable.
- Check for obstructions: Ensure the connector is fully seated and not partially engaged, which can cause arcing.
- Internal CT inspection: With power OFF, open the unit and locate the current transformer(s) around the output conductors. Verify they are properly clipped/secured and that the harness is firmly connected to the control board.
- Test at lower current: If the charger allows current limit adjustment, set a lower current and see if charging is stable. If E14 only occurs at higher currents, suspect cable or CT issues.
- Replace faulty parts: Replace the current sensor (CT) if wiring is intact but readings are incorrect. If the CT is good, the main control board may need replacement.
