Possible Causes
Loose pilot conductor in Nissan EVSE terminal block, Broken conductor inside charge cable, Thermal expansion causing intermittent contact on control board connector, Vehicle inlet pin making poor contact
How to Fix / Troubleshooting
Safety first: Turn OFF the breaker before opening the EVSE or handling wiring.
- Observe pattern: Note if interruptions occur when the cable is moved or when temperature changes (e.g., sun exposure).
- Inspect cable strain relief: Check for movement of the cable where it enters the Nissan wallbox. Excessive flexing can break internal conductors.
- Check terminal tightness: With power OFF, open the EVSE and tighten the pilot and low-voltage terminals on the control board.
- Wiggle test (careful): After re-energizing, gently move the cable near the EVSE and connector while monitoring charging. If movement causes dropouts, the cable assembly likely needs replacement.
