Charger starts charging but frequently stops and restarts; vehicle alternates between ‘Charging’ and ‘Ready’

Safety first: Repeated interruptions can indicate overheating or wiring issues.

• Step 1 – Observe breaker: Watch the breaker during a charge. If it feels hot or trips, have it replaced by an electrician.
• Step 2 – Check for pattern: Note whether interruptions occur at high current only. Try reducing the charger’s max current in the app and see if stability improves.
• Step 3 – Inspect wiring: With power OFF, retorque the input lugs in the charger and inspect for discoloration or melted insulation.
• Step 4 – Cable flex test: During a low-current charge, gently move the cable. If movement causes drops, the cable conductors may be broken internally.

Persistent instability after these checks suggests internal component failure (e.g., contactor, GFCI module) and warrants professional diagnosis.
