VDIAGTOOL V200 PRO Upgrade Kit – Automotive Power Circuit Probe Tester with 30 Back Probes (12/24V)

Overview

The VDIAGTOOL V200 PRO Upgrade Kit combines breadth of function with practical ease for auto electrical diagnostics. Built to help you understand circuit behavior, locate shorts, and verify component operation, it supports 12/24V systems with portable, battery-free operation. Expect a tangible sense of clarity when tracing wires, testing live circuits, and validating sensor or relay activity in everyday vehicles and work trucks alike.

Key capabilities

• AC/DC voltage testing to confirm a circuit is live or dormant, with immediate orientation on the circuit side you are testing.
• Resistance and diode checks to assess continuity and diode health without removing components.
• Circuit open tests, polarity checks, continuity tests, and ground verification for quick fault isolation.
• Component activation to simulate real-world operation (lights, motors, wipers, fans) for faster troubleshooting.
• Signal and sensor circuit testing to help locate root causes after ECU fault codes are retrieved.
• Comprehensive relay, fuse, and trailer light testing for broader electrical system review.

What you get

• V200 Pro automotive circuit tester main unit for versatile diagnostics.
• 30 back probe kit for harness connectors and sensors, enabling safe, non-destructive probing.
• Back probe pins (15), banana plug to alligator clip leads (5), wire piercing probes (5), and nickel-plated copper alligator clips (5) for diverse test setups.
• 15 multi-angle back probes (90°, 135°, straight) with 0.07 mm needles, suitable for testing connectors and sensors up to 30V.

How it helps your workshop

Switch between testing modes with a single tap. In Mode I, activate the Probe Tester to check AC/DC voltage, resistance, and diode behavior. In Mode II, use the breaker finder to locate open connections, broken wires, or current leaks without damaging insulation. This single kit serves DIYers, technicians, service bays, and training environments, and it works across cars, SUVs, trucks, trailers, and marine vessels within the 6–42V DC range.

The 30-piece probe lead set supports fast diagnostics and reduces the need to strip wires. The included 15 multi-angle probes and the 5-color alligator clips help you stay organized during testing, while the wire piercing probes allow quick connections to weather-seal connectors without damage. Power is drawn directly from the vehicle’s battery or cigarette lighter, eliminating the need for an extra power source. A practical companion for everyday repairs, it also makes a thoughtful gift for enthusiasts who enjoy hands-on diagnostics.

Reliability and support

Backed by a 3-year warranty, 24/7 assistance, and a 60-day no-questions-asked return window, the V200 PRO Upgrade Kit is designed to help you test with confidence and flexibility in real-world conditions.
