9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Vehicle does not start. | Jump starter battery low; incorrect connection; vehicle battery completely dead. | Recharge jump starter; check cable connections for correct polarity; allow more time for the jump starter to provide initial charge to the vehicle battery before attempting to start. |
| Smart cable shows red light or no light. | Reverse polarity; short circuit; low battery on jump starter. | Disconnect and re-check connections for correct polarity (red to +, black to -); ensure clamps are not touching; recharge jump starter. If red light is on with a beep, it indicates reverse polarity. Correct the connection. If red light is on without a beep, it indicates low battery, recharge the jump starter. |
| Jump starter not charging. | Faulty cable or adapter; unit malfunction. | Try a different USB cable and power adapter; contact support if issue persists. |
