Safety Guidelines
Because of the possibility of personal injury, always use extreme caution when
working with batteries. Follow all BCI (Battery Council International) safety
recommendations.
Battery posts, terminals, and related accessories contain lead and lead
compounds, chemicals known to the state of California to cause cancer and birth
defects or other reproductive harm. Wash hands after handling.
WARNING—REQUIRED BY CALIFORNIA PROP. 65: Battery posts, terminals, and
related accessories contain lead and lead compounds, chemicals known to
the state of California to cause cancer and birth defects or other reproduc-
tive harm. Wash hands after handling.

Preparations Before the Test
Before connecting the tester, clean the battery posts or side terminals with
a wire brush and a mixture of baking soda and water. When testing side-
post batteries, install and tighten lead terminal adapters. A set of adapters is
included with the tester.
IMPORTANT: Do not test at steel bolts. Failure to install terminal adapters or
installing terminal adapters that are worn or dirty may result in inac-
curate test results. To avoid damage, never use a wrench to tighten the
adapters more than ¼ turn.
If you are testing in the vehicle, make sure all accessory loads are o, the key is
not in the ignition, and the doors are closed.

Battery Test Results
Decision Interpretation
GOOD BATTERY Return the battery to service.
GOOD-RECHARGE Fully charge the battery and return it to service.
CHARGE & RETEST Fully charge the battery and retest. Failure
to fully charge the battery before retesting
may cause inaccurate results. If CHARGE &
RETEST appears again after you fully charge the
battery, replace the battery.
REPLACE BATTERY Replace the battery and retest. A REPLACE
BATTERY result may also mean a poor
connection between the battery cables and the
battery. After disconnecting the battery cables,
retest the battery using the out-of-vehicle test
before replacing it.
BAD CELL-REPLACE Replace the battery and retest.
24 VOLT SYSTEM 24-volt system detected. Disconnect batteries
and test individually.
READY TO INSTALL Battery has just been activated and is ready to
install in vehicle (Motorcycle only)
NEEDS CHARGE Fully charge battery and retest using BEFORE
DELIVERY. (Motorcycle only)
Failure to fully charge the battery before

Decision Interpretation
NO PROBLEMS System is showing normal output from the alternator.
NO OUTPUT No alternator output detected.
√ Check all connections to and from the alternator,
especially the connection to the battery. If the
connection is loose or heavily corroded, clean or
replace the cable and retest.
√ If the belts and connections are in good working
condition, replace the alternator. (Older vehicles
use external voltage regulators, which may require
only replacement of the voltage regulator.)

Decision Interpretation
LOW OUTPUT Alternator not providing sufcient current to power the
system’s electrical loads and charge the battery.
√ Check the belts to ensure the alternator is rotating
with the engine running. Replace broken or
slipping belts and retest.
√ Check the connections from the alternator to
the battery. If the connection is loose or heavily
corroded, clean or replace the cable and retest.
HIGH OUTPUT Alternator voltage output exceeds the normal limits.
√ Make sure there are no loose connections and
the ground connection is normal. If there are no
connection problems, replace the regulator. Most
alternators have a built-in regulator that requires
replacing the alternator. In older vehicles that
use external voltage regulators, you may need to
replace only the voltage regulator.
EXCESSIVE
RIPPLE
Excessive AC ripple detected.
√ One or more diodes in the alternator is not
functioning or there is stator damage.
