Decision
The starter voltage is low and the battery is
discharged. Fully charge the battery and repeat the
starter system test.

The starter voltage is high but the cranking amps are
low.
Low Current
The engine didn't start and the test was aborted or
the vehicle's starting profile was not detected and the
Starter Test was skipped.

Test Results - Alternator
Decision
The output from the alternator is normal.
CHARGING
NORMAL
No output detected. Check belts to ensure alternator
is rotating when engine is running.
√
Check all alternator connections including to
NO OUTPUT
the battery. Clean or replace if necessary and
retest.
√
If the belts and connections are in good working
condition, replace alternator or external voltage
regulator.
Alternator not providing enough current to power
electrical loads and charge the battery.
√ Check belts to ensure the alternator is rotating
LOW
with the engine running.
OUTPUT
√ Check alternator connections to and from the
battery. If loose or heavily corroded, clean or
replace the cable and retest.
Alternator voltage to the battery exceeds normal
limits of a functioning regulator.
√ Check for loose and normal ground
HIGH
connections. If no connection problems are
OUTPUT
found, replace the regulator.
The normal high limit of a typical automotive
regulator is 14.5 volts +/–0.5. Refer to the
manufacturer specifications for the correct limit,
which may vary by vehicle type.
Test Results - Diode
Decision
One or more diodes in the alternator are not
functioning or there is stator damage, which is
shown by an excessive amount of AC ripple current
supplied to the battery.
EXCESSIVE
RIPPLE
√ Make sure the alternator mounting is sturdy and
that the belts are in good shape and functioning
properly. If the mounting and belts are good,
replace the alternator.
OPEN PHASE
Replace the alternator.
