booster battery and the other end of same cable to
positive (+) terminal of discharged battery (Figure 9).
On positive ground vehicles, connect jumper cables
between negative (-) battery terminals.
Figure 9 - Proper Jumper Cable Connections
(Negative Ground Vehicles Shown)
On negative ground vehicles, attach one end of the
remaining jumper cable to the negative terminal of
the booster battery and the other end to a ground at
least 304 mm (12 inches) from the battery of the
vehicle being started (Figure 9). (DO NOT connect
directly to the negative post of the dead battery.)
The ground connection must provide good elec-trical
conductivity and current carrying capacity.
On the positive ground vehicles, connect jumper cable
between positive (+) terminal of booster battery and
ground on the stalled vehicle.
CAUTION - TAKE CARE TO BE SURE THE CLAMPS
FROM ONE CABLE DO NOT INADVERTENTLY
TOUCH THE CLAMPS ON THE OTHER CABLE.
DO NOT LEAN OVER THE BATTERY WHEN MAK-ING
AVOID MOVING, HOT OR ELECTRICAL HAZARDS
SUCH AS FANS, MANIFOLDS AND SPARK PLUG
TERMINALS WHEN CONNECTING CABLES.
Be sure everyone is standing away from vehicles.
Start the engine of the vehicle with the booster
battery. Wait a few minutes, then attempt to start the
engine of the vehicle with the discharged battery.
Do not operate the starter for more than 15 seconds.
Wait at least 15 seconds between starting attempts
to allow starter motor to cool. If the engine does not
start after several cranking attempts, check to be
sure that the clamps are secure. If the engine still
continues to not start, refer to the appropriate service
manual for troubleshooting procedures.
After starting, allow the engine to return to idle
speed. Remove ground cable connection from the
vehicle with discharged battery. Then remove the
other end of the same cable from the booster
Remove the other cable by disconnecting from the
discharged battery first and then disconnect the
opposite end from the booster battery.
10. Remove and discard cloths covering battery vents.
A battery test should be performed whenever battery
trouble is suspected.
Battery testing will determine if:
Battery is satisfactory and can remain in service.
Battery should be recharged before placing it back in
Battery must be replaced.
A complete battery test, as outlined below, will include
State of Charge Test
Battery Capacity (Load) Test
CAUTION - WHEN PERFORMING BATTERY TEST,
OBSERVE RULES OF SAFETY. REFER TO
ALWAYS FOLLOW INSTRUCTIONS OF TEST
STEP 1. VISUAL INSPECTION
Visually Inspect the outside of the battery for
obvious damage such as cracked or broken
case or cover which would allow electrolyte loss.
Check for terminal damage. If obvious physical
damage Is found, replace the battery. If
possible, determine the cause of damage and
Check electrolyte level.
On maintenance free type batteries, access to
battery cells can be obtained as follows:
Side Terminal Batteries:
Use a knife blade to cut through top plaque cen-
ter section. (Cut on dotted lines.) Pry up ends of
vent manifold with a screwdriver. Remove mani-
