J1772 connector is difficult to insert or remove from the vehicle inlet.

Safety first: Do not force the connector; this can damage both the charger and vehicle inlet.

• 1. Visual inspection: Examine the connector for cracks, melted areas, or obvious deformation. Check that the latch moves freely.
• 2. Clean connector: Use compressed air and a soft brush to remove dust and debris. Do not insert metal objects into the pin area.
• 3. Check pin alignment: Look for bent or recessed pins. If pins are misaligned, the connector should be replaced; do not attempt to bend pins back.
• 4. Replace connector assembly: If mechanical damage is present, replace the entire J1772 connector or output cable assembly per Besenergy specifications.

When to call a professional: For connector replacement, contact a qualified technician.
