The ultimate diagnostic tool for automotive wiring and sensors! This Digital DC Circuit Line Tester is an essential tool for troubleshooting electrical systems in modern BS-4 & BS-6 bikes, scooters, cars, and commercial vehicles. Featuring a real-time digital LCD voltage display and bidirectional dual-color LED indicators, it allows you to test power, ground, shorts, and open circuits from 3V to 48V DC safely without risking damage to sensitive ECUs or EFI sensors.

• Backlit LCD Digital Display: Shows exact voltage readings (3V-48V DC) with 0.1V accuracy.
• Dual-Color LED Polarity Indicator: Red light indicates Positive (+), Green light indicates Negative/Ground (-).
• ECU & Sensor Safe: High-impedance design draws minimal current, protecting sensitive engine control units (ECUs) and microprocessors.
• Sharp Stainless Steel Probe: Heavy-duty, sharp metal point for piercing wire insulation and reaching tight connectors.
• Flexible Coiled Spring Wire: Heavy-duty PU coiled cord extends up to 2.4 meters for front-to-back testing.
• Rugged Workshop Build: Heat-resistant body and heavy-duty grounding alligator clip for daily professional use.
