Possible Causes

Worn or loose contacts in J1772 handle, Corroded pins in vehicle inlet, Undersized or damaged cable conductors, Loose internal terminal connections

How to Fix / Troubleshooting

Safety first: Stop charging immediately if components are too hot to touch. Turn off power at the breaker before internal inspection.

Steps to troubleshoot:

  • Inspect handle contacts: Look for discoloration, pitting, or deformation of the J1772 pins. Replace the handle if contacts are damaged.
  • Check vehicle inlet: Examine the vehicle inlet pins for corrosion or burning. If present, the vehicle should be serviced.
  • Internal terminals: With power OFF, tighten all high-current terminals inside the Blink unit, including line, load, and contactor connections.
  • Monitor temperature: After corrective actions, run a short charge and periodically check temperature. If overheating persists, reduce current setting or replace the cable assembly.

Persistent overheating is a fire risk. Replace any suspect components rather than attempting to repair contacts.
