Keep in mind that high current components such as starter
motor will also trip the circuit breaker.
NOTE:
Here is an example for this application.
●
●
●
●
Remove the blown fuse from the fuse box.
Use the probe tip to activate each of the fuse contacts.
While the circuit breaker trips is a short circuit. Record the
number or color of the wire.
Trace the wire as far as possible.

If you are tracing a short circuit in the brake light circuit, you will
know that the wiring harness must pass through the wire at the
door sill, Locate the color-coded wire in the harness and
expose it.
While in component activation interface select MOMENT
mode. Use the probe tip to contact the marked wire, press the
“UP” button to trigger power supply.
If the circuit breaker tripped, you have verified the shorted wire.
Cut the wire and power supply each end with probe tip again.
Follow the wire in the shorted direction and repeat this process
until the short is located.
In most cases, a short circuit will appear as a blown fuse or a
tripping of an electrical protection device (such as a circuit breaker
tripping).
This is the best place to start check the short circuit.
Following &
Locating
short circuits
Press “OK” button to trigger power supply.
●
The RED led light will ON and LCD screen will display values of
VDC, AMP and VCC, if the VDC value is almost the same as VCC
and AMP value is minimum approach to 0A. it means this is not
true ground. Otherwise, if probe circuit breaker tripped or display
OVERLOADED, It probably the ground.
