Contact the probe tip to the negative terminal of the component, the LED indicator should
light RED.
While keeping an eye on the red LED indicator, quickly depress and release the power switch
rearward (-). If the red indicator changed instantly from RED to GREEN 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 high amperage component (i.e., starter motor).
If the circuit breaker tripped, reset it by depressing the reset button.
WARNING: With this function a vehicle’s fuse can be blown
or tripped if grounding the contact in series with it.
Depress the rocker
switch rearward
to ground the horn.
