CHECKING FOR BAD GROUND CONTACTS
Probe the suspected ground wire or contact with
the probe tip.
Observe the green LED indicator.
Depress the power switch forward then release.
If the LED indicator changed from GREEN to
RED, this is not a true ground.
If the circuit breaker tripped, this circuit is
more than likely a direct ground. Keep in mind
that high current components such as starter
motors will also trip the circuit breaker.
FOLLOWING AND LOCATING SHORT CIRCUITS
In most cases a short circuit will appear by a
fuse or a fusible link blowing or a protection
device tripping (i.e., a circuit breaker). Here is
the best place to begin the search.
Remove the blown fuse from the fuse box. Use
the testers tip to energize each of both contacts
USING THE LIGHT AND TONE
The HC-CARGO 211083 has the option of a light
and tone. Once connected to a good battery,
the light and the tone will be activated.
The light illuminates the area you are testing
and is a great asset for seeing in dark areas.
The tone feature enhances the polarity signal.
When the tip is contacted to a positive circuit,
a high pitch tone will sound off. When the tip is
contacted to a negative circuit, a low pitch tone
will sound off. The tone can be toggled on or off
by pressing the audio tone On/Off button.

in the fuse box. The side which trips the tester
circuit breaker is the shorted circuit. Take note
of this wire's identification code or color. Follow
the wire as far as you can along the wiring
harness, for instance if you are following a short
in the brake light circuit you may know that the
wire must pass though the wiring harness at
the door sill. Locate the color-coded wire in
the harness and expose it. Probe through the
insulation of the wire with the tester tip and
depress the power switch forward to energize
the wire. If the tester circuit breaker tripped
you have verified the shorted wire.
Cut the wire and energize each end with the
tester tip. The wire which trips the tester
circuit breaker again will lead you to the
shorted area.
Follow the wire in the shorted direction and
repeat this process until the short is located.
