ACTIVATING COMPONENTS ON
VEHICLE
To activate components with positive (+) voltage: Contact
the probe tip to the positive terminal of the component, the
green negative sign “-” LED should light. Indicating continuity
to ground. While observing the green indicator, quickly de-
press and release the power switch forward (+). If the green
indicator went out and the red positive sign (+) LED came on,
you may proceed with further activation. If the green indica-
tor 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 allowing it to cool
down (15 sec.) and then depress the reset button.
Warning: Haphazardly applying voltage to certain circuits can
cause damage to a vehicle’s electronic components. There-
fore, it is strongly advised to use the vehicle manufacturer’s
schematic and diagnosing procedure while testing.
