BATTERY TEST PROCEDURE
1. If testing in-vehicle, make sure vehicle loads (lights, etc.)
are off and the key is removed. Connect the tester clamps
to the battery: red to positive (+), black to negative (–).
Rock each clamp back and forth to make a good connec-
tion. The rating system in use will fl ash, then the display
will show a .C.C.A value from which to start.
2. Scroll to the battery's rating.
3. Press the TEST key.
4. Read the results:

NOTE: A REPLACE reading when testing in the
vehicle may mean a poor connection between the
vehicle's cables and the battery. Disconnect the
battery cables and retest before replacing the battery.
If conn shows in the display, there is a bad connection.
Disconnect the clamps and reconnect. Make sure to rock the
clamps back and forth to make a good connection.
If the screen fl ickers or shows lines ( - - - ), the battery is too
low (< 8 volts) to test. Fully charge the battery and retest.
CHARGING SYSTEM TEST PROCEDURE
1. Connect to the battery.
NOTE: The battery must be good and fully charged
to do this test.
2. Press the V button to read live voltage.
3. Start the vehicle.
4. Read the voltage while the car is running:
If the Volts reading is between 13.3 volts and 15.5 volts
= Charging System OK
If the Volts reading is greater than 15.5 volts
= Charging System Problem. Check regulator.
If the Volts reading is less than 13.3 volts
= Charging System Problem.
Check connections, wiring, and alternator.
