  • Weight0.185 kilograms
  • TypeVoltmeter
  • Tests 6-24V DC circuits on cars, trucks, trailers
  • Bright LED shows voltage level, spare bulb included
  • Spring wire stretches 135 inches for reach anywhere
  • Sharp steel probe with rubber guard pierces wires safely
  • Weighs 0.185 kg, UL 61010-1 and CE certified

Wide DC Range

The WINAMOO circuit tester covers 6 to 24 volts DC, making it suitable for standard automotive electrical systems. A bright LED bulb indicates circuit status and its intensity changes with the measured voltage. The kit includes one replacement LED bulb for extended service life.

Professional and DIY Use

Technicians and hobbyists who need to check headlights, taillights, turn signals, fuse connections and faulty sockets will find the sharp stainless steel probe and protective rubber tip practical. Users requiring AC voltage measurement, continuity testing, resistance readings or work on systems exceeding 24 volts should select a different instrument.

135-Inch PU Spring Wire

The 135 inch polyurethane spring wire provides reach around the vehicle while remaining lighter and more flexible than standard cable. A large alligator clip allows secure one-hand attachment to either positive or negative ground for bidirectional testing.

Questions about this item

What voltage source must the vehicle provide for the 6-24V tester to operate?

The tester works on any 6-24V DC system, so the vehicle battery or circuit under test must supply within that range.

Can the alligator clamp connect to either a positive or negative ground on an older vehicle?

Yes, the clamp can attach to negative or positive ground while the probe touches the opposite side for bidirectional testing.

How will I know the LED bulb is indicating voltage correctly after I pierce a wire with the steel probe?

The LED brightness changes with the measured voltage, confirming the circuit is live and the tester is functioning.
