CTIVATING ELECTRICAL COMPONENTS
To activate components with positive (+) voltage:
Contact the probe tip to the positive terminal of the component, the LED indicator should light
GREEN.
While keeping an eye on the green indicator, quickly depress and release the power switch for-
ward (+). If the green indicator changed instantly from GREEN to RED you may proceed with
further activation. If the green indicator went off at that instant or if the circuit breaker tripped,
the Power Probe has been overloaded. This could happen for the following reasons:
• The contact is a direct ground.
• The component is short-circuited.
• The component is a high current component (i.e., starter motor).
If the circuit breaker tripped, reset it by depressing the reset button.
Warning: Haphazardly applying voltage to certain circuits can cause damage to a vehicle’s
electronic components. Therefore, it is strongly advised to use the correct schematic and
diagnosing procedure while testing.
TRICK: When powering-
up components, you can
increase the life of your
Power Probe switch if
you fi rst press the switch,
then contact the tip to the
component. The arcing
will take place at the tip
instead of the contacts of
the switch.
