| The third release in the Power Probe line of diagnostic tools for auto electrical systems, the Power Probe III is the most revolutionary automotive circuit tester to date*. Packed with quick diagnostic power and multiple capabilities, this small, but powerful tool allows automotive technicians to literally speed through regularly scheduled maintenance and the troubleshooting of problems on automotive electrical systems, saving time and money. How Does it Work?
After connecting the Power Probe III'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 volt meter or reconnecting hookup clips from one battery pole to the other. The power switch allows you 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. And yes, the Power Probe III is short circuit protected. It tests for bad ground contacts instantly without performing voltage drop tests and locates short circuits without wasting precious fuses. It tests for continuity with the assistance of its auxiliary ground lead. Also, with a flip of the power switch, you will know instantly that your Power Probe III is functioning without running to the battery as you would otherwise have to do with simple test lights. Finally, the unit's 20-foot cable (extendable 40-feet) allows you to test along the entire length of the vehicle without constantly searching for ground hookups. Together, these features make the Power Probe III an absolute must for automotive technicians at all levels who are looking for a fast and accurate solution to electrical systems diagnostics.  5 powerful electrical auto diagnostic modes in 1 tool

View larger. | Five Modes in One Tool
True to its design to provide auto technicians with a single tool for all their electrical systems diagnostic needs, the Power Probe III is packed with five powerful diagnostic modes. These include: Power Probe Mode, which indicates the average voltage level of the circuit; Negative Peak Mode, which monitors a positive circuit and captures the lowest voltage that it has dropped to; Positive Peak Mode, which monitors the probed circuit and captures the highest detected voltage; Peak to Peak Mode, which measures the difference between the positive and negative peak voltage levels over a 1 second period; and Threshold Level Setting Mode, used to adjust the threshold voltage in Power Probe Mode for peak to peak detection and signal monitoring. Standard Features: - Built-in Flashlight.
- Audio tone test indicator.
- Volt meter and short circuit indicator.
- Relay and component tester and continuity tester.
- Bad ground indicator.
- Circuit breaker protected.
- Cable, with extension allowing for 40-feet of coverage
- Blow molded hard case for protection.
