First, attach the test clips to the clamps
(surrounding the battery posts). Next, hold the
amps probe in the same orientation it will be
when clamped to the battery ground lead but hold
it next to the lead so that it can be zeroed
before it is attached.

Next, AutoTest checks the battery. The amount of
time AutoTest takes to test the battery depends
on the state of charge of the battery being
tested. AutoTest allows more time for a
discharged battery to come good during charge
than it does for a well charged battery.

The test battery was too discharged to reveal a
current drain at the start of the managed test
(when it is usually performed). Because the amps
probe has been measuring high amps during
cranking and charging, it must be re-zeroed
before looking for a small key-off current drain.

resistance to below 100m? within a short period

Disable the ignition by removing the high tension
coil lead from the distributor and connecting it
to ground. Disable the fuel pump to prevent
unburnt fuel damaging the catalytic converter by
removing the fuel pump relay or fuse. AutoTest
automatically detects the start of cranking and
counts down from 15 seconds to show the
recommended cranking time remaining.

The Starter Test Results Screen The results table
shows the cranking volts and amps after 5, 10 and
15 seconds of cranking. When the amps readings
are high, either there is excessive engine
friction placing high loads on the starter motor
or the starter motor is faulty.

The Starter Test Results Screen The voltage
readings can give an indication of the loaded
voltage performance of the battery. If the
battery is fully charged and the amps readings
are around ½ the batterys rated CCA then the
voltage after 15 seconds is the batterys Loaded
Voltage (LV). LVs below 9.6 volts indicate a
reject battery.

The Starter Test Results Screen If the test
battery was rated at 380 CCA (SAE) and it was
fully charged for the test, the results screen
above would indicate a reject battery. The test
battery is delivering plenty of amps and will
start an engine, but its voltage isnt holding
up under load, which indicates the battery will
soon fail.

The Starter Test Results Screen When cranking is
stopped before 15 seconds (in this case just
after 12 seconds) AutoTest will display as much
data as was gathered during the shortened
crank. Had cranking stopped before 10 seconds
(but after 5) there would only be two rows of
results. If cranking stopped before 5 seconds
there would only be one.
