Circuit Tester 3-28V Cordless Automotive Voltage Probe

A cordless automotive circuit tester for checking live circuits on 3-28V systems without needing a separate ground lead or clip. It gives clear feedback through light, sound and vibration, making it easier to confirm power when working in tighter spaces or where visibility is poor.

Used for auto electrical fault finding, this 3-28V live wire tester suits garages, mobile mechanics and anyone carrying out vehicle maintenance or wiring checks. It is handy when tracing power, checking circuits during servicing, or working around areas where a trailing lead can get in the way. The tester is also suitable for checks around ECM sensors, transducers and airbag-related circuits where a quick live-circuit confirmation can save time.

Built for regular workshop and garage use, the cordless design helps when access is awkward and there is less room to manage extra leads. The 3V to 28V operating range covers many common automotive electrical checks, while the combined buzzer, light and vibration alerts give more than one way to confirm a reading. A V-groove guard is included for added safety during use, and the supplied alkaline batteries mean it is ready to use straight from the pack. For regular electrical diagnosis, it is a practical option to keep close to hand for quick checks without extra setup.
