The Power Probe 4 Master Combo Kit combines the Power Probe 4, ECT3000 and various accessories to provide the ultimate combination of diagnostic and circuit-testing capabilities.

The Power Probe 4 provides simplified testing of Motors, Lights, Relays, and Sensors, and even Fuel Injectors. Also, like all Power Probe circuit-testers, it supplies Power and Ground for functional component testing on or off the vehicle. The ECT3000 will help you trace short and open circuits quickly and accurately.

The Power Probe PP3EZ includes all the powerful testing modes and features of the Power Probe III 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.
