Troubleshooting
Device Not Turning On / Charging Issues
- Ensure the device is fully charged. Connect it to a power source using the provided USB-C cable and a compatible charger.
- Check the charging cables and adapter for any damage.
Vehicle Not Starting
- Verify that the smart jumper cable clamps are securely connected to the correct battery terminals (red to positive, black to negative).
- Check the indicator lights on the smart jumper cable. A solid green light indicates a correct connection. If the "Reverse" light is on, re-attach the clamps.
- If the battery is deeply discharged, use the BOOST function by pressing and holding the BOOST button on the smart cable until the indicator turns solid green. Attempt to start the vehicle immediately after.
- Ensure the GOOLOO A5 unit has sufficient charge (at least 50% recommended for jump-starting).
Tire Inflator Not Working / Inaccurate Pressure
- Ensure the pump tube is securely connected to both the GOOLOO A5 and the tire valve.
- Check that the correct inflation mode and target pressure are selected on the display.
- Verify the unit has enough battery charge for inflation.
- If pressure readings seem inaccurate, cross-reference with a separate, calibrated tire pressure gauge.
