Charger shows E16 and the vehicle reports a charging system error; charging may start briefly then stop.

Safety: An insulation fault can lead to electric shock. Turn OFF the breaker and do not use the charger until the issue is resolved.

• 1. Inspect cable and handle:
  • Look for cracks, cuts, or abrasions on the AMPROAD cable.
  • Check the handle for signs of water ingress or cracks.
• 2. Dry the unit:
  • If the charger is outdoors, check for water inside the enclosure.
  • Dry thoroughly and improve sealing (replace gaskets or cable glands if needed).
• 3. Internal inspection:
  • With power OFF, inspect the power board for contamination (dust, insects, corrosion) between high-voltage components.
  • Clean with appropriate electronics cleaner and a soft brush.
• 4. Insulation test (qualified only):
  • Use a megohmmeter to test insulation resistance between live conductors and ground according to AMPROAD specifications.
• 5. Replace faulty parts:
  • If the cable fails insulation tests, replace the AMPROAD output cable & handle assembly.
  • If the board is damaged, replace the power board.
