CHECKING FOR BAD GROUND CONTACT
Probe the suspected ground wire or contact with the
probe tip.
Observe the green negative sign “÷“ LED. Depress the
power switch forward then release. If the green negative
sign “÷“ LED went out and the red positive sign “+“ came
on, this is not a true ground. If the circuit breaker
tripped, this circuit is more than likely a good 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 an electrical protection device
tripping (i.e., a circuit breaker). This is the best place to
begin the dearch. Remove the blown fuse from the fuse
box.
Use the Power Probe tip to activate and energize each
of the fuse contacts. The contact which trips the HC-
CARGO 211097 circuit breaker is the shorted circuit.
Take note of this wire’s identification code or color. Fol
-
low 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 in-
sulation with the Power Probe tip and depress the power
switch forward to actovate and energize the wire. If the
Power Probe circuit breaker tripped you have verified
the shorted wire. Cut the wire and energize each end
with the Power Probe tip. The wire end which trips the
Power Probe circuit breaker again is the shorted circuit
and will lead you to the shorted area. Follow the wire in
the shorted direction and repeat this process until the
short is located.
RED/GREEN POLARITY INDICATOR AND
AUDIO TONE
The “RED/GREEN Polarity Indicator“ lights-up when the
probe tip voltage matches the battery voltage within ±
0.5 V. This means that if you contact a circuit that is not
a good ground or a good hot, you will see this instantly
by the “RED/GREEN Polarity Indicator“ NOT lighting.
The Audio Tone runs parallel to the “RED/GREEN Pola-
rity Indicator“ and will also NOT react when contacting
a circuit that does not match the battery voltage within
± 0.5 V.
MODES
Using the advanced features and modes is optional.
However, understanding them will expand your
diagnosing capabilities. The LCD display indicates
voltage levels of the circuit along with an identifying
symbol showing what mode it is in. the additional
features contain 5 modes which gives specific
information about how the circuit is reacting.
The 5 mo-
des can be accessed by depressing the MODE button
and through each one.
Mode #1 Power Probe Mode:
While the HC-CARGO 211097 is in “Power Probe Mode“
and the probe tip is floating (not contacting a circuit), the
LCD backlight is on but the display is blank. If the audio
tone is turned on you will see a speaker symbol in the
lower right corner of the display.
Once you contact the probe tip to a circuit the LCD
display will indicate the average voltage level of the
circuit. The red/green polarity indicator (See section
Red/Green Polarity Indicator and Audio Tone) will
respond also, showing whether the circuit is positive or
negative.
A secondary feature in this mode is the peak threshold
detection and signal monitoring. When contacting a
signal generating circuit such as a speaker wire with
audio signals on it, the HC-CARGO 211097 detects
the peak to peak signals and displays the peak to peak
voltage in the display, the sound of the signals will be
monitored and heard through the HC-CARGO 211097
speaker. The peak to peak threshold levels are pre-
selected by the operator in “Mode 5“. See Mode #5 for
more information on
setting threshold levels.
Placing the HC-CARGO 211097 tip next to a sparkplug
wire (NOT probing directly), allows you to monitor the
sound of the ignition pulses at the same time display a
peak to peak reading. The HC-CARGO 211097 senses
the pulses in ignition wires through capacitive coupling
(DO NOT CONTACT PROBE TIP DIRECTLY TO THE
SECONDARY IGNITION CIRCUIT). By monitoring each
plug wire in this way you can locate missing cylinders.
Mode #2 Negative Peak Mode:
The Negative Peak Mode monitors a positive circuit
and captures the lowest voltage that it has dropped to.
To do this: Place the HC-CARGO 211097 in “Negative
Peak Mode“ by pressing and holding the mode button
for 1 second until you hear a low pitched beep and the
LCD display indicates a negative (÷) sign in the lower
left corner. The display should also indicate a reading
of “0.0“ with the probe floating. (This is because no
voltage is present). Probe the positive circuit you want
to test and tap the mode button once. The LCD display
will show the lowest detected voltage of the circuit. If the
circuit drops in
voltage at anytime, a new lowest reading will be
captured and displayed. You can then do a quick tap of
the mode button once again to reset the LCD display
and indicate the new voltage level on the circuit. Reset
the LCD display by doing a quick tap of the mode button
as often as necessary.
An APPLICATION for the use of the “Negative Peak
Mode“: Lets say you have a circuit that is suspect of
