Why are there sparks when connecting GYS STARTPACK PRO 12.24 Extender clamps to the vehicle battery?
- K
  Krista SandersAug 14, 2025
  Sparks may occur when connecting the clamps to the vehicle battery if the battery switch is turned ON, the voltage selector is on 12V or 24V, the voltage selector is in the wrong position, or there is a polarity inversion. To resolve this, turn the battery switch OFF, disconnect the voltage selector before connecting the clamps, ensure the selected voltage corresponds to the vehicle’s battery voltage, and verify the correct polarity on the battery.

What to do if GYS Extender cannot start the vehicle and the red LED flashes?
- S
  Susan AlvarezAug 18, 2025
  If the GYS Extender cannot start the vehicle and the red LED flashes, it could be due to discharged internal batteries, too many starting attempts without allowing recovery time, or an incorrect battery voltage. Recharge the machine to the maximum level and try again. Allow 3 minutes between starting attempts, and each start should not last more than 5 seconds. Also, ensure that the selected voltage corresponds to the voltage of the vehicle’s battery.

Why does the orange LED flash for more than 3 hours on GYS STARTPACK PRO 12.24 Extender?
- T
  Terry HendersonAug 27, 2025
  If the orange LED flashes for more than 3 hours and does not turn green on your GYS Extender, it means the charger has detected sulphated or deeply discharged batteries. The product will attempt to recover the battery with a specific charge of 16 hours.

Why is the red LED flashing on my GYS Extender?
- S
  Sharon SmithSep 3, 2025
  If the red LED on your GYS Extender flashes, it indicates that the battery voltage has dropped below 12.5V after a start or heavy consumption. To resolve this, charge the device after use. The red LED will then turn off.

Why do orange and green LEDs flash alternatively during GYS STARTPACK PRO 12.24 charge?
- R
  Ricky WhiteSep 6, 2025
  If the orange and green LEDs flash alternatively during the charge of your GYS Extender, it means the charger is on thermal protection because it is overheating due to high room temperature. The charger will automatically restart the charge once the temperature has dropped sufficiently.

What does it mean when orange and green LEDs are flashing on GYS STARTPACK PRO 12.24 after charging?
- J
  Joel RobinsonSep 10, 2025
  If the orange and green LEDs are flashing after 24 hours of charge on your GYS Extender, it indicates that the internal batteries are damaged and their voltage is not increasing despite the charge. Unplug the machine from the mains, and then restart the charge. If the problem persists, the batteries are damaged.
