How to Jump-Start a Motorcycle Using a Car Battery

Updated February 21, 2017

There is little that's more frustrating than discovering that your motorcycle won't start because its battery is dead. If the battery is drained, you can try to jump-start your motorcycle with another battery from a running engine. Motorcycle manufacturers recommend that you jump your bike from another bike, but if another motorcycle isn't available, you can jump-start your motorcycle from the battery of a car that isn't running. This is a fairly simple process that requires no tools.

  1. Turn off the engine of the car that you are using to jump-start your bike. If the car is running during the jump, the voltage produced by the car may overload your motorcycle battery's electrical capacity.

  2. Connect the positive lead of the jump lead to the positive terminal of your motorcycle battery.

  3. Connect the positive lead on the other end of the jump lead to the positive terminal of the car battery.

  4. Connect the negative lead of the jump lead to the negative terminal of the car battery.

  5. Connect the negative lead on the other end of the jump lead to the chassis of your motorcycle. Do not connect the negative lead to the negative terminal of your motorcycle battery, as doing so may cause an explosion.

  6. Turn on your motorcycle and leave it running.

  7. Disconnect the negative lead from the motorcycle chassis.

  8. Disconnect the opposite negative lead from the car battery.

  9. Disconnect the positive lead from the car battery.

  10. Disconnect the opposite positive lead from the motorcycle battery.
