Checking For Bad Grounds
Following & Locating Short Circuits
Red/Green Polarity Indicator & Tones
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.
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 search. 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 PP3S 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 with the
Power Probe tip and depress the power switch forward to activate 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. The Power Probe ECT3000 uses a wireless non-contact technique that guides
you to the short/open location.
The “ RED / GREEN Polarity Indicator” lights-up when the probe tip voltage matches the battery voltage
within ± 0.5 volts. 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 Polarity Indicator and will also NOT react when contacting a circuit that does not match
the battery voltage within ± 0.5 volts. This is a very useful function that automatically alerts you of any
excessive voltage drop in the circuit.

Flip Screen Function
The PP3S has the adiitional abilty to change the orientation of the display screen. Press the right menu
button to bring up the menu, then use the left button to scroll to “FLIP SCREEN” then press the right
button again. The display screen will now be inverted 180 degrees allowing the user to select either
display mode depending on the testing situation. Selecting the “FLIP SCREEN” function again to restore
the display to it’s original orientation.
