Current Draw - Key Off
CAUTION
Do not connect or disconnect the battery cable or
ammeter with the engine running. Damage will occur to
electrical components.
Connect an ammeter in series with the negative battery
cable. Check for current draw with the key off. If the draw
is excessive, loads should be disconnected from the
system one by one until the draw is eliminated. Check
component wiring as well as the component for partial
shorts to ground to eliminate the draw.
Current Draw - Key Off:
Maximum of .01 DCA (10 mA)
OCV - Open Circuit Voltage Test
Battery voltage should be checked with a digital
multitester. Readings of 12.6 volts or less require further
battery testing and charging. See the following chart and
“Load Test”.
NOTE: Maintenance Free batteries should be kept at
a high state of charge during storage. If the battery is
stored or used at a low state of charge, hard crystal
sulfation will form on the plates, reducing the
efficiency and service life of the battery.
Use a volt/ohm meter to test battery voltage.

Load Test
CAUTION
To prevent shock or component damage, remove spark
plug high tension leads and connect securely to
engine ground before proceeding.
A battery may indicate a full charge condition in the OCV
test, but still may not have the storage capacity
necessary to properly function in the electrical system.
For this reason, a battery capacity or load test should be
conducted
whenever
poor
battery
performance
is
encountered.
To perform this test, use a load testing device that has an
adjustable load. Apply a load of three times the ampere-
hour rating. At 14 seconds into the test, check battery
voltage. A good 12V battery will have at least 10.5 volts.
If the reading is low, charge the battery and retest.
