CTIVATING COMPONENTS IN THE
V
EHICLE
(PPM)
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 depress 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 activa-
tion. 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 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. Therefore, it is strongly advised to use the vehicle manufacturer’s schematic and diagnos-
ing 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.
