How to Fix / Troubleshooting
Safety first: An isolation fault is serious and can lead to electric shock. Immediately stop using the charger.
- 1. Disconnect and dry:
- Unplug from mains and vehicle.
- If the charger has been exposed to rain or flooding, move it to a dry, ventilated area.
- Allow at least 24–48 hours to dry completely. Do not use artificial heat sources.
- 2. Visual inspection:
- Check the exterior for cracks, open seals, or obvious water entry points.
- 3. Do not attempt internal cleaning unless qualified:
- Opening the housing exposes high-voltage components.
- 4. If E19 persists after thorough drying:
- Internal insulation or isolation components may be permanently damaged.
- Contact NRGkick support for professional insulation testing and repair or replacement.
