Activating Components w/Ground
Contact the probe tip to the negative terminal of the component, the LED indicator should light
RED
.
While observing
red positive
sign “+” LED, quickly depress and release the power switch rearward (-). If
the red indicator went out and the
green negative
sign (-) 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 have happened for the following reasons:
• The contact is a direct positive voltage.
• The component is short-circuited.
• The component is a very 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: With this function, if you are contacting a protected circuit, a vehicle’s fuse can be blown
or tripped if you apply ground to it.
