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
activation. 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.
Depress the rocker
switch rearward
to ground the horn.
