Jump Starting.
1.) Verify the voltage and chemistry of the battery.
2.) Confirm the HD battery clamps are connected to
the correct polarity battery terminals.
3.) Make sure all of the vehicle’s power loads
(headlights, radio, air conditioning, etc.) are turned off
before attempting to jump start the vehicle.
4.) Press the Power Button to begin jump starting. All
LEDs will flash, indicating that all LEDs are properly
functioning. If you are properly connected to the
battery, the White Boost LED will illuminate and the
charge level LEDs will chase. If the battery clamps are
connected in reverse, the Red Error LED will illuminate.
Reverse the connections to clear this error and then
the White Boost LED will illuminate. The White Boost
LED is illuminated, when the GB150 is ready to jump
start your vehicle.
5.) Try starting the vehicle. Most vehicles will
immediately start. Some vehicles may require the
GB150 to be connected for up to 30 seconds before
starting. If the vehicle does not start right away, wait
20-30 seconds and try again. Do not attempt more
than five (5) consecutive jump starts within a fifteen
(15) minute period. Allow the GB150 to rest for fifteen
(15) minutes before attempting to jump start the
vehicle again.
6.) Once you have started your vehicle, disconnect the
battery clamps, and remove the GB150.
