The TOPDON CT100 is a professional-grade automotive circuit tester engineered to bring speed, precision, and reliability to electrical diagnostics. Unlike basic test lights that can miss underlying issues, the CT100 features a dedicated load test function that allows technicians to verify circuit capacity and identify aging batteries or high-resistance connections in seconds. With a wide testing range of 3.3V to 65V, this versatile tool is compatible with 12V, 24V, and 36V systems, making it an essential asset for everything from passenger cars and RVs to heavy-duty trucks and commercial vehicles.
Designed for intuitive use in dark or cramped engine bays, the CT100 utilizes a high-clarity LCD backlit display alongside instant polarity alerts. The screen glows red for positive and green for negative, providing immediate visual confirmation while protecting sensitive vehicle electronics through built-in anti-reverse technology. The device is entirely battery-free, drawing power directly from the circuit under test to eliminate maintenance and downtime. It also features smart status indicators that warn of overvoltage or overheating, ensuring safe operation during rigorous diagnostic workflows.
Built for the demands of a busy shop, the CT100 comes equipped with an extra-long 12.5-foot oil-resistant cable, allowing you to reach from the battery to the rear of most vehicles without repositioning. The universal 4mm banana jack design supports interchangeable probes and clips, providing the flexibility needed to test fuses, trace wiring, and verify connector integrity with 0.1V resolution. Rugged, accurate, and easy to operate, the TOPDON CT100 takes the guesswork out of automotive electrical repair for professionals and dedicated DIYers alike.
