Message

NO PROBLEMS
System is showing normal
output from the alternator.
–
NO OUTPUT
No alternator output de-
tected.
R
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.
R
If the belts and connections are in good working condition, replace the alterna-
tor. (Older vehicles use external voltage regulators, which may require only re-
placement of the voltage regulator.)
LOW OUTPUT
Alternator not providing
sufficient current to pow-
er the system's electrical
loads and to charge the
battery.
R
Check the belts to ensure the alternator is rotating with the engine running. Re-
place broken or slipping belts and retest.
R
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.
R
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 de-
tected.
One or more diodes in the alternator is not functioning or there is stator damage.
CHARGE BATTERY
The starter voltage is low
and the battery is dis-
charged.
Fully charge the battery and repeat the starter system test.
REPLACE BATTERY If the battery test result
was REPLACE or BAD
CELL.
The battery must be replaced before testing the starter.
SIDE POST
Test data was inconclusive
using the side post.
Retest using side post adapters.
REMOTE POST
Data was inconclusive us-
ing the Remote post.
Retest at the battery terminals.

Additional Test Messages
For a more decisive result, the tester may prompt you for additional information. The messages in the following table
may appear before the tester can display a result.
Test Message
Action to be taken
BAT. TEMPERATURE
Select ambient temperature above or below 0
˚
C (32
˚
F).
CHARGE STATE
Select before or after battery has been charged.
SURFACE CHARGE DETECTED
Remove the surface charge before it begins testing. Testing will resume after charge has been re-
moved.
CHECK CONNECTION
One or both clamps are not making proper contact with the battery terminals.
ENGINE REV NOT
DETECTED PRESS
WHILE REVVING
Tester has not detected an increase in engine rpm
REVERSE CONNECTION
Clamps are connected in the wrong polarity: positive to negative or negative to positive.
SYSTEM NOISE CHECK LOADS Only with BATT. LOCATION INSIDE VEHICLE. BAT 125 has recognized active loads in the vehicle. En-
sure that all loads in the vehicle are deactivated, including opened doors and the ignition switch.
UNSTABLE BATTERY
Out-of-vehicle. Weak battery, should be charged and retested.
WIGGLE CLAMPS
Clamps are not making good contact with battery terminals
