VOLTAGE DROP TEST (Charging Cable Test)
The screen will show you
where to make your connections.
The large clamps need to be
connected to the alternator
terminals. The red clamp to the
alternator positive terminal, black
to the alternator ground. The small
clamps need to be connected to
the battery posts. The small red
clamp to the b, the small
black clamp to the battery.
Select the V DROP Test from
the main menu.
Select Charging Cable Test.
Test in process, please wait.
To set the test current, press the
Test current box and a numeric
keypad will appear. Enter in the
alternator output for the vehicle you
are testing. Press the Done button
and then press the Start Test button.
If the combined voltage drop of
the positive and negative circuit
is less than 500mV, the voltage
drop test passes. If the voltage
drop test fails you should start by
troubleshooting and repairing the
side of the circuit with the highest
voltage drop.
