- Page 2 INTRODUCTION Thank you for purchasing the NEW Power Probe III (PP3). The PP3 is our most revolution- ary circuit tester to date. The PP3 literally speeds you through the diagnosing of 12 to 24 volt automotive electrical systems. After connecting the PP3’s clips to the vehicle’s battery, the auto- motive technician can determine at a glance, the voltage level and the polarity of a circuit with out running for a voltmeter or reconnecting hook-up clips from one battery pole to the other.

Unroll the Power Probe cable. Connect the battery hook-up 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 PP3 is fi rst connected to a battery (power source), it will sound a quick high and then low beep and go into “Power Probe Mode (PPM) (See Mode #1 on page 10) and the 2 bright white LEDs... -

IRCUIT REAKER In Power Probe Mode (Mode #1) with a the circuit breaker tripped, the LCD will display the symbol “C B”. (see page 11-12 for detail) All other functions of the PP3 are still active. This means that you can still probe a circuit and observe the voltage reading. -
Page 6: Continuity Testing
(PPM) ONTINUITY ESTING While the PP3 is in Power Probe 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 PP3 indicates continuity using 2 resistance levels. -

(PPM) CTIVATING OMPONENTS IN While the PP3 is in Power Probe Mode and by using the Power Probe tip in connection with the aux- iliary 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. -

(PPM) CTIVATING COMPONENTS IN THE EHICLE 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 (+). -

(PPM) CTIVATING LECTRICAL OMPONENTS W ROUND 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. -

ODES The Power Probe III has been designed to work the same as the previous Power Probe circuit testers. Using the ad- vanced 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 you what mode it is in. The additional features contain 5 new modes which give you specific information about how the circuit is reacting. -
