Connecting The Jumper Cables
1. Connect the positive (+) end of the jumper
cable to the remote positive (+) post of the
discharged vehicle.
2. Connect the opposite end of the positive
(+) jumper cable to the positive (+) post of
the booster battery.
3. Connect the negative end (-) of the jumper
cable to the negative (-) post of the
booster battery.
4. Connect the opposite end of the negative
(-) jumper cable to a good engine ground
(exposed metal part of the discharged
vehicle's engine) away from the battery
and the fuel injection system.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause
the battery to explode and could result
in personal injury. Only use the specific
ground point, do not use any other exposed
metal parts.
5. Start the engine in the vehicle that has
the booster battery, let the engine idle a
few minutes, and then start the engine in
the vehicle with the discharged battery.
CAUTION!
Do not run the booster vehicle engine
above 2,000 rpm since it provides no
charging benefit, wastes fuel, and can
damage booster vehicle engine.
6. Once the engine is started, remove the
jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-) end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.
2. Disconnect the opposite end of the nega-
tive (-) jumper cable from the negative (-)
post of the booster battery.
3. Disconnect the positive (+) end of the
jumper cable from the positive (+) post of
the booster battery.
