activation. (Figure 12) If the green LED went off at that instant or if the circuit breaker
tripped, the tool has been overloaded. This could happen for the following reasons:
(1) The contact you are probing is a direct ground.
(2) The component you are testing is short-circuited.
(3) The component is a very high current component (i.e., starter motor).
If the circuit breaker is tripped, reset it by waiting for it to cool down (15 sec.)
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 diagnosing procedure while testing.
NOTE: When powering up components, you can increase the life of power switch if
you first 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.

3.6 Testing Trailer Lights and Connections
While the tool in DC Voltage mode, clip the auxiliary ground lead to the trailer
ground , probe the contacts at the jack and then apply voltage to the probe tip. This
lets you check the function and orientation of the connector and trailer lights. (Figure
13)
If the circuit breaker tripped, that contact is likely a ground. Reset the circuit breaker
by letting it cool down for 15 seconds.
