The circuit tester can be used to test continuity, test voltage polarity, check motors, check lights, track and locate short circuits, test poor ground contact, etc.It can check switches, relays and the on-off of diodes, fuses and circuits, which can help you reduce diagnostic time in automotive electrical systems
The cable length is approximately 16 feet, allowing you to easily test any electrical system
The unit has a short-circuit protection function, which can detect poor grounding contact immediately
After simplyconnecting the device to the battery of the vehicle, the car technician canconduct the positive and negative current of the battery to the tip by shakingthe power switch forward or backward, and the operation is simple, Can help youquickly identify positive and negative polarity of electric cables and plugs ofvehicles. When the probe tip contact to the positive electrode, the RED lighton. When the probe tip contact to the negative electrode, the GREEN light on
This is a comprehensive 6-24V DC test kit, please do not use it under AC voltage
