5.12 Activating Components in the Vehicle
Figure 15
1) While the tool in DC Voltage mode, contact the probe tip to the positive terminal of
the component, the green LED should light, indicating continuity to ground.
2) Observe the green LED, quickly depress and release the rocker switch forward. If
the green LED went out and the red LED came on, you may proceed with further
activation. (Figure 15) 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:
The contact you are probing is a direct ground.
The component you are testing is short-circuited.
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 (about 1 minute.)
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 rocker 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.
