Charger shows E15 and the current display (if present) reads zero; vehicle may show ‘Charging paused by EVSE’.

Safety first: Turn off power before opening the charger or testing pilot circuits. The pilot line carries low voltage but is referenced to high-voltage circuitry.

• 1. Basic reset:
  • Power-cycle the charger and vehicle.
  • Try a different vehicle if available to rule out car-side issues.
• 2. Inspect pilot wiring:
  • Check the J1772 connector for damage to the small pilot pin.
  • Inspect the cable for cuts or crushing that could short the pilot conductor.
• 3. Continuity test (advanced):
  • With power off, measure continuity of the pilot wire from the main control board connector to the J1772 pilot pin.
  • Check for shorts between pilot and other conductors.
• 4. Board-level issue:
  • If the cable is intact, the PWM pilot generator on the main control board is likely defective.
  • Replace the main control board; firmware reprogramming may be required per Megear instructions.

Pilot signal faults generally require board or cable replacement rather than field repair of components.
