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.

Depress the rocker 

switch rearward to
