When the tester touches the positive pole, the LED should be red; when it touches the negative pole, the LED should be GREEN. The electric circuit tester is also used to check the continuity of switches, relays, diodes, fuses, and circuits. 【Electrical Tester for Component Activation and Testing】For professionals or car enthusiasts, this continuity tester is a great tool. The automotive short circuit tester can activate the components in/out of the vehicle's electrical system. The LED indicator and buzzer prompt can easily test and check whether the components are defective, or whether the rated current of the component is higher than the rated current of the tester. 【Automotive Circuit Tester for Grounding Test】The design of the circuit breaker finder is perfectly designed and feels comfortable. It is equipped with a 4M extended detection line, covering the front to the rear of the vehicle and easily detecting the entire vehicle circuit system. The automotive circuit tester kit has a grounding prompt device. If the LED indicator turns green and the buzzer sounds, it means that the grounding is good. If it is not, the LED remains red and there is no beep. 【Tracking and Locating Short Circuits】The electrical tester uses advanced high-sensitivity probes to provide you with fast and accurate detection. Using the continuity tester can save a lot of time to troubleshoot the car wiring circuit, to quickly and accurately find the faulty wire and its fault point.

  • ANCEL PB100 Automotive Power Circuit Probe Tester, 12V 24V Car Electrical System Test Tool Kit AC DC Digital Voltage Resistance Short Finder, Relay Fuse Tester, Trailer Light Diagnostic Thermometer
    Bestseller #1
    ANCEL PB100 Automotive Power Circuit Probe Tester, 12V 24V Car Electrical System Test Tool Kit AC DC Digital Voltage Resistance Short Finder, Relay Fuse Tester, Trailer Light Diagnostic Thermometer (1069)
      【What is a PB100 Probe Tester?】With the PB100 probe tester, you can check voltage and ground signals in a typical DC circuit. However, the kicker is that you can also use it to send voltage and ground signals. It works like a test light that can power circuits or provide a good known ground. This way, you can effectively test components and circuits without having to break out the old alligator clips and jumper wires. You can power or ground a circuit directly through the top of the device. 【What Can an ANCEL PB100 Do?】In fact, this is a very handy tool for many functional circuit tests. For example, you can use it to turn on a blower motor. You can run power window motors, windshield wipers, and even rear window defrosters. But be careful when turning on anything with a motor, especially something with a motor-driven linkage. 【Voltage Indicator】The LED indicator on the front of the unit will show you the battery voltage when it is connected. You can use it to determine a whole range of things. You can even do a quick check of the alternator by plugging it in and starting the car. The voltage should go from about 12.6 volts to 14.0 volts. This is also useful if you have a situation where a power supply has a large voltage drop, if you notice low voltage on certain branches when checking fuses, etc. 【Circuit Protection】The PB100 has a built-in 8-amp circuit breaker to prevent circuit overload and overheating. Unlike a normal test lamp, this device can conduct direct battery current into the circuit you touch with it. Any time you backfeed a circuit, you need to know what you are doing. The breaker will protect the circuit, but 8 amps is still enough to do a lot of damage with the wrong wire. 【Trailer Wiring】A recurring source of frustration for technicians across the country, especially those who service trailers exposed to road salt or salt water. ​The PB100 Circuit Tester features a long 20-foot cable that allows you to make the initial connection directly to the vehicle's battery, while providing easy access to connect the trailer harness at the rear of the vehicle. 【24/7 Technical Support】ANCELs official store offers a 30-day money back guarantee, 2 year warranty and lifetime customer support. For technical support and any problems with the order, please contact us via buyer-seller messages to solve the problem.
