INTRODUCTION
Thank you for purchasing the Power Probe 3EZ (PP3EZ). The
PP3EZ includes all the powerful testing modes and features
of the Power Probe 3S plus now includes 2 new modes - EZ
Learning Mode and EZ Diagnostics Mode. The PP3EZ speeds
you through the diagnosing of 12 to 24 volt automotive electrical systems. After connecting the PP3EZ’s clips to the vehicle’s battery, the automotive technician can determine at a
glance, the voltage level and the polarity of a circuit without
running for a voltmeter or reconnecting hook-up clips from
one battery pole to the other. The power switch allows the
automotive technician to conduct a positive or negative battery current to the tip for activating and testing the function of
electrical components without wasting time with jumper leads.

It allows you to follow and locate short circuits without wasting
precious fuses. The Power Probe can also test for continuity
with the assistance of its auxiliary without running to the battery as you would otherwise have to do with simple test lights.
The PP3EZ’s 20ft (extendable) cable allows you to test along
the entire length of the vehicle without constantly searching
for ground hook-ups.
Do not use the equipment for measurements on CAT II, CAT
III & CAT IV. An absolute must for every automotive technician
looking for a fast and accurate solution to electrical systems
diagnostics.
Before using the Power Probe 3EZ please read the instruction
booklet carefully.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may
be impaired.
Warning! When the PP3EZ rocker switch is depressed battery current/voltage is conducted directly to the tip which
may cause sparks when contacting ground or certain circuits.
Therefore the power energized Power Probe could ignite
these vapors. Use the same caution as you would when using
an arc welder.

HOOK UP AND QUICK SELF-TEST
Unroll the Power Probe cable. Connect the RED battery hookup clip to the POSITIVE terminal of the vehicle’s battery. Connect the BLACK battery hook-up clip to the NEGATIVE terminal of the vehicle’s battery. When the PP3EZ is first connected
to a battery (power source), it will sound a quick start up tone
and then go into Voltmeter Mode (See Mode #1) and the 2
bright white LEDs (dual headlights) will be on to illuminate the
test area of the probe tip.
TURNING AUDIO TONE ON & OFF
While the PP3EZ is in Voltmeter Mode, press the left button to
toggle the tone on or o. When the left button is pressed, if a
short high beep is heard, this means the audio tone is turned
on. If a short low beep is heard, the audio tone has turned o.

CIRCUIT BREAKER
In Voltmeter Mode (Mode #1) with the circuit breaker tripped,
the display will show “Circuit Breaker Tripped”(see page 11-12
for detail) All other functions of the PP3EZ are still active. This
means that you can still probe a circuit and observe the voltage reading. When the circuit breaker is tripped, the PP3EZ
will NOT be able to conduct battery current to the tip even
when the power switch is pressed. Intentionally tripping the
breaker and using the PP3EZ to probe can be considered an
added precaution against accidental pressing of the power
switch.

INTRODUCTION TO “EZ”
The Power Probe 3EZ is the latest addition to the Power
Probe line of circuit testers. It includes all the powerful testing
modes and features of the Power Probe 3S and now includes
2 new modes- EZ Learning Mode and EZ Diagnostics Mode.
EZ Learning Mode will guide you through a step by step
familiarization of the PP3EZ, showing you how to operate the
PP3EZ and how the probe responds in certain testing conditions.
EZ Diagnostics Mode will help guide you through specific
vehicle or component tests and let you know if readings obtained are acceptable or outside of the desired specification.
EZ Learning Mode – Scroll the Menu down using the Left
Button until EZ LEARNING is highlighted on the menu. Select
EZ LEARNING by pressing the Right Button. EZ Learning will
now take you through a step by step process illustrating how
the probe responds and the dierent types of readings that
can be obtained. This mode is to be used for familiarization
and guidance only and is not a mode used for actual circuit
testing.
Once EZ LEARNING mode is selected, it must be scrolled
through from start to finish before it will exit EZ LEARNING
mode. You can also exit EZ Learning by disconnecting power from the probe and the probe will enter normal test mode
when re-connected. NOTE: If you see a flashing screen in the
menu it means go to that selection and press enter.

EZ DIAGNOSTICS
EZ Diagnostic Mode – Scroll the Menu down using the Left
Button until EZ DIAGNOSTICS is highlighted on the menu. Select EZ DIAGNOSTICS by pressing the Right Button. EZ DIAGNOSTICS are preset test modes for dierent vehicle system
tests.
The available tests listed are: Battery Check, Charge Test,
Fuse Test, Voltage Test, Component Test, 5V Ref.
Each test section includes a readable QR code that will access online video content explaining the test procedure.
5V REF mode is used together with the Power Probe Tek 5V
Adapter Tip (# PPT5VA). With the Adapter Tip installed on the
probe and applying power, the probe will no longer output full
battery voltage. The 5 Volt Adapter will only output a current
limited 5V that can be used as a reference voltage to safely
power and test sensor and computer circuits.

CONTINUITY TESTING
While the PP3EZ is in Voltmeter Mode, and by using the Power Probe tip in connection with chassis ground or the auxiliary
ground lead, continuity can be tested on wires and components attached or disconnected from the vehicle’s electrical
system.
The PP3EZ indicates continuity using 2 resistance levels.
When the Power Probe tip has a resistance to ground less
than 20K Ohms but greater than approx. 650 Ohms the LCD
will indicate “00.0” volts but no Green “-” LED. But when the
resistance to ground less than approx. 650 Ohms the LCD will
indicate “00.0” volts and also the Green “-” LED. The higher
resistance continuity function is useful for checking Spark Plug
Wires, (disconnected from ignition) Solenoids and magnetic
pickup coils, and the lower resistance continuity for testing relay coils and wiring. However the best way to prove continuity
of connections to either Ground or Battery is to power up the
connection using the Power Switch. If the Circuit Breaker trips
you know that you have a good solid low resistance connection.

ACTIVATING COMPONENTS IN HAND
While the PP3EZ is in Voltmeter Mode and by using the Power
Probe tip in connection with the auxiliary ground lead, components can be activated right in your hand, thereby testing
their function. Connect the negative auxiliary clip to the negative terminal or ground side of the component being tested.
Contact the probe to the positive terminal of the component,
the green negative sign “-“ LED indicator should light GREEN
indicating continuity through the component.
While keeping an eye on the green LED negative sign, quickly
depress and release the power switch forward (+). If the green
negative sign “-“ LED went out and the red positive sign “+”
came on, you may proceed with further activation. If the green
negative sign “-“ LED went o at that instant or if the circuit
breaker tripped, the Power Probe has been overloaded. This
could happen for the following reasons:
• The contact you are probing is a direct ground or negative
voltage.
• The component you are testing is short-circuited.
•The component is a very high current component (i.e., starter
motor).
If the circuit breaker is tripped, reset it by waiting for it to cool
down (15 sec.) and then depressing the reset button.

TRAILER LIGHT CONNECTIONS
1. Connect the PP3EZ to a good battery.
2.Clip the auxiliary ground clip to the trailer ground.
3. Probe the contacts at the jack and then apply voltage to
them. This lets you check the function and orientation of the
connector and trailer lights. If the circuit breaker tripped, that
contact is likely a ground. Reset the circuit breaker by letting
it cool down (15 sec.) and depressing the reset button until in
clicks into place.

ACTIVATING COMPONENTS ON
VEHICLE
To activate components with positive (+) voltage: Contact
the probe tip to the positive terminal of the component, the
green negative sign “-” LED should light. Indicating continuity
to ground. While observing the green indicator, quickly depress and release the power switch forward (+). If the green
indicator went out and the red positive sign (+) LED came on,
you may proceed with further activation. If the green indicator went o at that instant or if the circuit breaker tripped, the
Power Probe has been overloaded. This could happen for the
following reasons:
•The contact is a direct ground.
•The component is short-circuited.
•The component is a high current component (i.e., starter
motor).
If the circuit breaker tripped, reset it by allowing it to cool
down (15 sec.) and then depress the reset button.
Warning: Haphazardly applying voltage to certain circuits can
cause damage to a vehicle’s electronic components. Therefore, it is strongly advised to use the vehicle manufacturer’s
schematic and diagnosing procedure while testing.

ACTIVATING COMPONENTS WITH
GROUND
Contact the probe tip to the negative terminal of the component, the LED indicator should light RED. While observing red
positive sign “+” LED, quickly depress and release the power
switch rearward (-). If the red indicator went out and the green
negative sign (-) came on you may proceed with further activation. If the green indicator went o at that instant or if the
circuit breaker tripped, the Power Probe has been overloaded. This could have happened for the following reasons:
• The contact is a direct positive voltage.
• The component is short-circuited.
• The component is a very high current component (i.e., starter
motor).
If the circuit breaker tripped, reset it by allowing it to cool
down (15 sec.) and then depress the reset button.
WARNING: With this function, if you are contacting a protected
circuit, a vehicle’s fuse can be blown or tripped if you apply
ground to it.
