When disconnecting battery terminals, always
disconnect the main ground terminal (negative)
first. When reconnecting, always connect the
main ground terminal (negative) last.
NOTICE
If there are other ground cables
connected to the battery (such as
engine ECM), disconnect those
ground cables first, then remove the
main battery ground cable (negative).
Electronic modules may be damaged
when additional grounds are connected/
disconnected without the main battery
ground connected. Disconnect the main
battery ground (negative) last.
battery Jump-Starting and Charging
NOTICE
It is very important to exercise caution
when charging batteries or jump-starting
an engine in a vehicle with a modern
electrical system. Electrical control units
can be damaged by voltage spikes or
current surges created by jump-starting.
To minimize any risk for damage to the
electronic components, see the following
guidelines for charging/jump-starting. If the
batteries are discharged to the point where
they do not have enough stored energy to start
the engine, they should be recharged using a
low-charge voltage, not to exceed 16 volts.
Do not use battery chargers with “boosting”
capability. These produce high voltage that
will cause damage to the vehicle electrical and
electronic components.
If the engine needs to be started immediately,
use starting batteries. Connect the cables as
follows:
1. 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
(Figure 131) (unless vehicle is equipped
with optional jump-start posts). This way,
the cranking current is carried through the
proper starter wiring.
2. Connect the jumper cables to the positive,
or “hot,” terminal first and the ground
terminal last. When disconnecting the
cables, disconnect 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 connections quickly and
firmly. Do not permit vehicles to touch
each other when jump-starting.
