BATTERY LOAD TEST
A fully charged battery must have cranking capac-
ity. To provide the starter motor and ignition system
enough power to start the engine over a broad range
of ambient temperatures. A battery load test will ver-
ify the actual cranking capability of the battery.
WARNING: IF BATTERY SHOWS SIGNS OF FREEZ-
ING, LEAKING, LOOSE POSTS, OR EXCESSIVELY
LOW ELECTROLYTE LEVEL, DO NOT TEST. ACID
BURNS OR AN EXPLOSIVE CONDITION MAY
RESULT.
(1) Disconnect and isolate the battery negative
remote cable first. Then disconnect and isolate the
positive Jump Start cable.
(2) Use a suitable Volt/Ammeter/Load tester con-
nected between remote battery terminals (Fig. 2) and
(Fig. 3). Check the open circuit voltage of the battery.
Voltage should be equal to or greater than 12.4 volts.
If below 12.4 volts charge battery, perform the same
test at the battery. Remove both battery cables the
negative cable first. If the voltage is still below 12.4
perform Battery Charging procedures.
(3) Rotate the load control knob of the carbon pile
rheostat to apply a 260 amp load. Apply this load for
15 seconds to remove the surface charge from the
battery, and return the control knob to off (Fig. 4).
(4) Allow the battery to stabilize for two minutes,
and then verify open circuit voltage.
