Battery Jump Starting and Charging
To access the batteries on a vehicle
equipped with side fairings, open the fair-
ing access cover. On the second battery
from the front there are special, longer
posts installed to accept jumper cables.
When jumping batteries to start an engine,
it is important that the jumper cables are
connected directly from one set of batteries
in one vehicle to the other set of batteries
in the other vehicle (unless vehicle is
equipped with optional Emergency Start
System). This way the cranking current is
carried through the proper starter wiring.

Connect the jumper cables to the positive,
or “hot” terminal first and ground terminal
last. When disconnecting the cables, dis-
connect the ground terminal first. Connect
the jumper cable clamps to the discharged
battery first and to the booster battery last.
Avoid creating sparks by making all con-
nections quickly and firmly. Do not permit
vehicles to touch each other when jump
starting.
Do not attempt to jump-start a vehicle
equipped with Delco Maintenance Free
batteries if the test indicator is light yel-
low. Replace the battery instead.
Jump-starting may cause battery to ex-
plode causing skin burns from acid or
serious personal injury or death.
WARNING
Always wear eye protection when work-
ing around batteries to prevent the risk
of injury due to contact with sulfuric
acid or an explosion.
