About this item

• Tracking & Locating Short Circuits, Overload Protection: Topdiag Electrical Circuit Tracer has a built-in short circuit protection. If overloaded, its internal circuit breaker finder will trip to ensure the safety of users and prolong the service life of the tester. Circuit tester automotive with large battery clip, can carry more load. Support wide input voltage range from 9V to 70V, also support 12V cars and 24V trucks.
• 20FT Extension Cable, Built-in Flashlight: Cable length is gonna be important when troubleshooting the rear of a truck! Topdiag electric tester comes with extra 20ft extension cable in addition to its own 20ft cable, allowing you to access any position of the vehicle and test it. Ideal for trailer wiring, it can be tested along the vehicle without having to find a suitable ground point. The built-in flashlight is convenient for detection, even in the dark or dim environment, it can provide the best view for who need to work in night.
• 4 Working Modes: make circuit detection more simple. DC Voltage, AC Voltage, Resistance, Tone On/ Off. 1) DC Voltage mode can read DC voltage with 0.1V resolution. 2) AC Voltage can get Min & Max voltage, duty cycle and frequency quickly. 3) Resistance mode to read resistance between tip and auxiliary ground wire. 4) Unique Tone On/ Off Design is really useful when working in dim areas, it can judge the circuit voltage according to the volume of the sound.
• Same Function As PP3: This P100 Circuit Tester is an absolute must if you're trying to diagnose and electrical issues or think an electrical part is bad. Does everything the more expensive ones do and at a better price.
• Car Circuit Tester Kit: The Topdiag automotive circuit breaker finder tool is capable of turning components on and off within an electrical system or equipment. It is tailored for automotive technicians and enthusiasts. By triggering the signal produced by the component, you can effectively determine the integrity of various parts, including the blower motor, power window motor, windshield wiper, rear window defroster, lights, radiator fans, fuel injectors, etc. Additionally, this automotive circuit tester tool allows you to activate components either in your hand, inside the vehicle, or with a ground connection.
• Time Saver & Quick DIY Test: Don't know much about cars? The P100 Power Circuit Probe Tester allowed to track down the problem in minutes, much faster than regular multimeter to trace out the wiring.
