How to Install a Battery on a Harley Motorcycle
The Harley-Davidson motorcycle is powered by a 12-volt battery, which supplies power to the lights, turn signals and horn of the bike. On some Harley models, a push start button has been added to make it easier to start the motorcycle. This also needs power from the battery. When you try to start the Harley and nothing happens, the battery has most likely died out and needs to be recharged or replaced.
