RECOMMENDED JUMP STARTING
PROCEDURE
Service Interval: As required
1.
Check the weak battery for terminal corrosion
(white, green, or blue "snow"), it must be
cleaned off prior to jump starting, Clean and
tighten connections as necessary
CAUTION
Corrosion or loose connections can cause
unwanted electrical voltage spikes at anytime
during the jump starting procedure.
Do Not attempt to jump start with loose or
corroded battery terminals or damage to the
engine may occur.
DANGER
Jump starting a weak battery that is cracked,
frozen, has low electrolyte level, or an
open/shorted battery cell, can cause an
explosion resulting in serious personal injury.
Do Not jump start a weak battery if these
conditions exist.
2. Make sure the booster is a good and fully
charged lead acid battery at 12.6 volts or
greater. Use properly sized jumper cables (4 to
6 AWG) with short lengths to reduce voltage
drop between systems. Make sure the cables
are color coded or labeled for the correct
polarity.
CAUTION
Connecting the jumper cables incorrectly
(wrong polarity) can immediately damage the
electrical system.
Be certain of battery terminal polarity and
jumper cable polarity when hooking up
batteries.
NOTE: The following instructions are adapted from
the SAE J1494 Rev. Dec. 2001 – Battery Booster
Cables – Surface Vehicle Recommended Practice
(SAE – Society of Automotive Engineers).
WARNING
Batteries contain acid and produce explosive
gasses.
Shield the eyes and face from the batteries
at all times.
Do Not lean over the batteries.
NOTE: Be sure the vent caps are tight and level.
Place a damp cloth, if available, over any vent caps
on both batteries. Be sure the vehicles do not
touch and that both electrical systems are off and at
the same rated system voltage. These instructions
are for negative ground systems only.
3.
Connect the positive (+) cable to the positive (+)
terminal of the discharged battery.
4. Connect the other end of the positive cable to
the positive terminal of the booster battery.
5. Connect the black negative (-) cable to the
other terminal (negative) of the booster battery.
6. MAKE THE FINAL CONNECTION ON THE
ENGINE BLOCK OF THE STALLED VEHICLE
(NOT TO THE NEGATIVE POST) AWAY
FROM THE BATTERY. STAND BACK.
7. Start the vehicle and remove the cables in the
reverse order of connection (the engine block
(black) connection is the first to disconnect).
