Harley Davidson does not recommend jump starting a motorcycle. However, there may be
circumstances when it is necessary to do so. Therefore, we suggest jump starting be performed
as follows:
Be sure jumper cables touch only appropriate battery
terminals or ground. Allowing jumper cables to touch each
other can result in sparks and a battery explosion, which
could result in death or serious injury. (00072a)
Explosive hydrogen gas, which escapes during charging,
could cause death or serious injury. Charge battery in a
well ventilated area. Keep open flames, electrical sparks
and smoking materials away from battery at all times.
KEEP BATTERIES AWAY FROM CHILDREN. (00065a)
Harley Davidson motorcycles have a 12 Volt battery. Be
sure the booster vehicle has a 12 Volt system. Failure to
do so could result in vehicle damage. (00220a)
NOTE:
This procedure presumes the BOOSTER battery is in another vehicle.
1. Turn off all unnecessary lamps and accessories.
Positive Cable
2. See Jump Start Cable Connections. Connect one end of a jumper cable to the
DISCHARGED battery positive (+) terminal (1).
3. Connect the other end of the same cable to the BOOSTER battery positive (+) terminal (2).
Negative Cable
Do not connect negative ( ) cable to or near the discharged
battery negative ( ) terminal. Doing so could cause a spark
and explosion, which could result in death or serious
injury. (00073a)
4. Connect one end of a jumper cable to the BOOSTER battery negative ( ) terminal (3).
