Possible Causes

Tripped or open circuit breaker, Loose line connections at breaker or charger, Failed internal AC-DC power supply, Blown internal fuse on control board

How to Fix / Troubleshooting

Safety first: Work on the supply circuit only if you are qualified. Turn off the main panel before tightening lugs.

Steps to troubleshoot:

  • Check breaker: Verify the dedicated EVSE breaker is in the ON position and has not tripped. Reset once if tripped; if it trips again, stop and investigate further.
  • Verify voltage: A qualified person should measure voltage at the charger input terminals to confirm presence of correct supply.
  • Inspect internal fuse: With power OFF and cover removed, locate any internal fuses on the main control board or power supply module. Replace only with identical type and rating if blown.
  • Check wiring: Tighten all line and ground connections inside the Blink unit and at the breaker. Look for burned insulation or discoloration.

If supply voltage is present and fuses are intact but the unit remains dead, the internal power supply module or main control board is likely defective and should be replaced by an EVSE technician.
