⚡ At a Glance
- • Voltage Range: Supports 3V–120V DC with a flexible 20cm coiled spring wire
- • Best for: DIY enthusiasts and professional mechanics for vehicle electrical troubleshooting
- • Not ideal for: Testing AC mains circuits or systems above 120V DC
Compact automotive circuit tester suited to vehicle electrical diagnostics across a wide DC range. LED polarity indicators and alligator clips enable bidirectional ground checks.
Safe Handling – With AS plastic handle
AS plastic construction resists electrical conduction and heat, creating a sturdy, non-slip grip. The handle design isolates the user from live contacts during probing.
Safer manual testing during fuse and wiring checks, reducing the risk of accidental shocks. Comfortable grip makes short diagnostic sessions less fiddly.
Versatile DC Testing – With 3–120V DC support
Wide-range circuitry reads voltages from 3V up to 120V DC, suitable for most vehicle systems. Flexible coiled spring wire extends reach while remaining compact.
Covers common car electrical checks from sensors to fuses without swapping tools. Coil lead reaches into tight engine bays while stowing neatly between uses.
Clear Readings and Polarity – With LED indicators and numerical display
LED indicators show polarity with red for positive and green for negative, while user feedback confirms a numerical voltage readout. Alligator clips allow secure connection to positive or negative grounds.
Immediate visual confirmation of polarity and exact voltage values makes fault-finding faster and more reliable. Hands-free clip connections free both hands for probing or repairs.
