About this item

• Car Circuit Tester Kit: This Topdiag automotive circuit breaker finder tool can activate components on/off-board electrical system/ equipment, is designed for car technician or car enthusiasts. By activating the signal generated by the component, you can accurately judged whether the component is intact, such as blower motor, power window motor, windshield wiper, rear window defroster, lights, radiator fans, fuel injectors, etc. Also, automotive circuit tester tool can activate component in your hand/ in the vehicle/ with ground etc.
• 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.
• 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.
• 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.
• 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.
• 20FT Extension Cable, Integrated Flashlight: Length of cable is crucial for examining the back of a truck! The Topdiag electric tester includes an extra 20ft extension cable on top of its own 20ft cable, giving you the ability to reach any area of the vehicle for testing. Great for trailer wiring, it can be tested throughout the vehicle without needing to locate a proper ground point. The integrated flashlight is handy for visibility, especially in low light conditions, providing optimal view for those working at night.
