Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Vehicle does not start. | Low charge on jump starter; incorrect cable connection; vehicle battery completely dead; engine too large for unit. | Ensure jump starter is fully charged. Check that clamps are securely connected to correct battery terminals. If battery is completely dead, it may require more time or professional assistance. Verify engine displacement is within specified limits (8.0L gas, 6.5L diesel). |
| Smart cable indicator light is red or flashing. | Incorrect connection; short circuit; reverse polarity; over-temperature. | Disconnect clamps and reconnect them correctly (red to positive, black to negative). Ensure clamps are not touching each other. Allow unit to cool down if it has been used extensively. |
| Unit not charging. | Faulty cable or adapter; loose connection. | Try a different Type-C cable and/or 5V USB adapter. Ensure the cable is firmly plugged into both the unit and the power source. |
| USB output not charging devices. | Low battery on jump starter; faulty USB cable; device not compatible. | Charge the jump starter. Try a different USB cable. Ensure your device is compatible with 5V USB charging. |
