5. Determine the polarity of the vehicle's battery terminals. The positive (POS, P, +) battery
terminal is usually larger in diameter than the negative (NEG, N, −) terminal. If you are
unsure, you should refer to the vehicle owner's manual.
6. Determine the ground system of your vehicle.
• If vehicle to be started has a negative ground system (this is most common):
a. Connect the red (+) cable clamp first to the vehicle's positive (red) battery terminal.
b. Next, connect the black (−) clamp to the vehicle chassis or a solid, non-moving,
metal vehicle component or body part. DO NOT clamp directly to negative battery
terminal or a moving part.
• If vehicle to be started has the positive battery terminal connected to chassis (this is rare
and usually found in older car models from the 1950s or earlier):
a. Connect the black (−) clamp first to vehicle battery's negative (black) terminal.
b. Connect red (+) clamp to vehicle chassis or a solid, non-moving, metal vehicle
component or body part. DO NOT clamp directly to positive battery terminal or a
moving part.
7. Observe the color of the Reverse Polarity Protection Indicator to see if the clamps are
properly connected.
• If the light is RED and the unit is beeping, DO NOT TURN ON THE JUMPER
SAFETY SWITCH!
a. Cable clamps need to be reversed.
b. Disconnect the black clamp first then the red clamp.
c. Reconnect and observe the indicator again.
• If the light is not illuminated and there is no beeping, turn on the Jumper Safety Switch.
a. Inside the vehicle, turn on the ignition switch and attempt to start the engine.
b. Crank a maximum of 3 seconds. If the engine does not start, wait 3 minutes before
the next attempt.
c. After the engine starts, turn off the Jumper Safety Switch.
d. Disconnect the clamps in the reverse order of connection prior to jumpstarting. Be
sure that the cables and clamps are securely stored.
8. Recharge the JumpBoost as soon as convenient.
