Using the Power Pro
One Wire Hookup Testing & Hookup Procedure
Use this procedure for
in-circuit testing a
component connected to
a harness.
Procedure
1. Set the Output Polarity Switch to the OFF position and the PWM Control
Knob to OFF.
2. Connect the tester’s power cable to the battery. The tester will power
up and perform a self test. Once the test is completed, the LED Readout
displays a zero.
Note: If the unit becomes unresponsive, remove and reconnect
the power cable connections to the battery.
3. Select the probe that most closely mates to the component’s harness and
connect it to a test lead.
4. Plug the test lead into the output jack
.
5. Connect the output lead to the component by back probing the drive side
of the component per the vehicle’s shop manual.
6. Set the Output Polarity Switch to + or – based on the component’s circuit
operation per the vehicle’s shop manual and rotate the PWM Control knob
to increase (or decrease) the amount (%) desired to test the component.
The amount of current the component is drawing is displayed in the LED
Readout.
7. Make note of the results and refer to the specifications listed in the vehicle’s
shop manual to determine the course of action needed for repairs.
