| The second release in the Power Probe line of diagnostic tools for auto electrical systems, the Power Probe II is a revolutionary automotive circuit tester*. Packed with quick diagnostic power and multiple capabilities, this small but powerful tool allows automotive technicians to speed through regularly scheduled maintenance and the troubleshooting of problems on automotive electrical systems, saving time and money.  Accurate and fast diagnostics for 6-24 volt automotive systems.

After a simple hookup of the Power Probe II to the vehicle's battery, the automotive technician can determine at a glance at the red/green LED indicator, if a circuit is positive, negative or open without reconnecting hookup clips from one battery pole to the other. The Power Probe II switch allows the automotive technician to conduct a positive or negative battery current to the tip for testing the function of electrical components without the use of jumper wires and it is short-circuit protected. It tests for bad ground contacts instantly without performing voltage drop tests, and allows you to follow and locate short circuits without wasting precious fuses. The Power Probe II can also test for continuity with the assistance of its auxiliary ground lead. With a flip of the power switch, you will know at a glance that your Power Probe is functioning without running to the battery as you would otherwise have to do with simple test lights. The Power Probe II's long cable allows you to test along the entire length of the vehicle without constantly searching for ground hookups. If you are not using the Power Probe II now in your electrical testing, you are spending too much diagnostic time. Polarity Testing
The Power Probe II makes polarity testing easy. Contacting the Power Probe II's tip to a positive (+) circuit will light the LED indicator red (the audio feature will sound a high pitched tone when contacting positive). Contacting the tip to a negative (-) circuit will light the LED indicator green (the audio feature will now sound a low pitched tone when contacting negative). Contacting the Power Probe II's tip to an open circuit will be indicated by the LED indicator not lighting. The Light and Tone Indicator
The Power Probe II has the option of a light and tone indicator. Once connected to a good battery, the light and the tone will be activated. The light illuminates the area you are testing and is a great asset for seeing in dark areas. 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 low pitch tone will sound off. The tone can be toggled on or off by pressing the audio tone on-off button. Activating Removed Components and Electrical Components
By using the Power Probe II tip together with the auxiliavry ground lead, components can be activated, thereby testing their function. Connect the negative auxiliary clip to the negative terminal of the component being tested and 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 II has been overloaded. It's as easy as that. A similar technique can also be used to activate electrical components using either positive or negative voltage. Checking for Bad Grounds and Short Circuits
To find bad grounds with the Power Probe II, probe the suspected ground wire or contact with the probe tip and while observing 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. To locate a short circuit, first remove the blown fuse from the fuse box, then 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 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 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 wire which 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.
