Warning!
''When the Power Probes switch is depressed battery current is conducted directly to the tip which may cause sparks when contacting ground or certain circuits. Therefore the Power Probe should NOT be used around flammables such as gasoline or its vapours. The spark of an energized Power Probe could ignite these vapours. Use the same caution as you would when using an arc welder.
The Power Probe is not to be used with 110/220-volt house current or Ac, it is only for use with 6-24-volt Dc systems.''
Instructions
HOOK-UP QUICK SELF-TEST
Unroll the Power Probe cable. Clamp the RED battery hook-up clip to the POSITIVE terminal of the vehicles battery. Clamp the BLACK battery hook-up clip to the NEGATIVE terminal of the vehicles battery. Rock the power switch forward (+), the LED indicator should light RED.
(The Probe will sound a high pitched tone in addition to the red light) Rock the power switch rearward (-), the LED indicator should light GREEN.
(The Probe will sound a lower pitched tone in addition to the green light
The Power Probe is now ready to use.
CONNTECTING
Contacting the Power Probe tip to a POSITIVE (+) circuit will light the LED indicator RED. The Probe audio feature will sound a high pitched tone when contacting positive.
Contacting the Power Probe tip to a NEGATIVE (-) circuit will light the LED indicator GREEN. The Probe audio feature will sound a lower pitched tone when contacting negative.
Contacting the Power Probe tip to an OPEN circuit will be indicated by the LED indicator not lighting Red.
CONTINUITY TESTING
By using the Power Probe tip together with the auxiliary ground test lead, continuity can be tested on wires and components that are disconnected from the vehicles electrical system.
When continuity is present, the LED indicator will light GREEN.
ACTIVATING REMOVED COMPONENTS
By using the Power Probe tip together with the auxiliary ground lead, components can be activated, thereby testing their function.
Connect the negative auxiliary clip to the negative terminal of the component being tested.
Contact the probe to the positive terminal of the component, the LED indicator should light GREEN indicating continuity through the component. While keeping an eye on the green LED indicator, quickly depress and release the power switch forward (+). If the green indicator changed instantly from GREEN to RED you may
proceed with further activation.
If the green indicator went off at that instant or if the circuit
breaker tripped, the Power Probe has been overloaded. This could happen for the following reasons:
¢â‚¬¢ The contact is a direct ground or negative voltage.
¢â‚¬¢ The component is short-circuited.
¢â‚¬¢ The component is a high amperage component (i.e., starter motor).
If the circuit breaker is tripped, reset it by depressing the reset button.
TESTING TRAILER LIGHTS AND CONNECTIONS
1. Connect the Power Probe to a good battery.
2. Clip the auxiliary ground clip to the trailer ground.
3. Probe the contacts at the jack and apply voltage to them. This lets you check the function
and orientation of the trailer lights. If the circuit breaker tripped, reset it by depressing the
reset button.
ACTIVATING ELECTRICAL COMPONENTS
To activate components with positive (+) voltage:
Contact the probe tip to the positive terminal of the component, the LED indicator should light GREEN.
While keeping an eye on the green indicator, quickly depress and release the power switch forward
(+). If the green indicator changed instantly from GREEN to RED you may proceed with
further activation. If the green indicator went off at that instant or if the circuit breaker tripped,
the Power Probe has been overloaded. This could happen for the following reasons:
¢â‚¬¢ The contact is a direct ground.
¢â‚¬¢ The component is short-circuited.
¢â‚¬¢ The component is a high current component (i.e., starter motor).
If the circuit breaker tripped, reset it by depressing the reset button.
Warning: Haphazardly applying voltage to certain circuits can cause damage to a vehicles
electronic components. Therefore, it is strongly advised to use the correct schematic and
diagnosing procedure while testing.
ACTIVATING ELECTRICAL COMPONENTS WITH NEGATIVE (-) VOLTAGE
Contact the probe tip to the negative terminal of the component, the LED indicator should light RED.
While keeping an eye on the red LED indicator, quickly depress and release the power switch
rearward (-). If the red indicator changed instantly from RED to GREEN you may proceed
with further activation. If the green indicator went off at that instant or if the circuit breaker
tripped, the Power Probe has been overloaded. This could have happened for the following
reasons:
¢â‚¬¢ The contact is a direct positive voltage.
¢â‚¬¢ The component is short-circuited.
¢â‚¬¢ The component is a high amperage component (i.e., starter motor).
If the circuit breaker tripped it will reset itself in a few seconds.
WARNING: With this function a vehicles fuse can be blown or tripped if grounding the contact in series with it.
JUMPER LEAD FEATURE
The Power Probe negative battery hook-up lead and auxiliary ground lead are connecteddirectly through the Power Probe. By leaving the positive hook-up disconnected from the
vehicles battery, the Power Probe can be used as a long jumper lead.
Be careful to avoid short circuits and overloading when using this jumper function. The leads, in this configuration, are NOT protected by the Power Probes circuit breaker.
CHECKING FOR BAD GROUND CONTACTS FOLLOWING AND LOCATING SHORT CIRCUITS
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.
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 Power Probe tip to energize each of both contacts in the fuse box. The side which trips the Power Probe circuit breaker is the shorted circuit. Take note of this wires 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 Power Probe tip and depress the power switch forward to 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 wirewhich trips the Power Probe 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.
USING THE TONE
The Power Probe has of a tone. Once connected to a good battery, the tone will be activated. 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 lower pitch tone will sound off.
