Celinfto Automotive Circuit Fault Probe Tester – Portable 20A/48V 2-in-1 Wire Tracer with LED Display

Overview

The Celinfto Automotive Circuit Fault Probe Tester is a compact, high-precision diagnostic tool designed for quick, real‑world electrical troubleshooting on cars, trucks, SUVs, and motorcycles. It delivers real-time current readings across a usable range, helping you identify subtle circuit fluctuations and pinpoint fault points without guesswork. Designed for both DIY enthusiasts and professional technicians, this tester combines accuracy with practicality for everyday automotive diagnostics.

Why it stands out

• Real-time current sensing from 0.01A up to 19.99A, enabling precise monitoring of circuit behavior as you test components.
• High compatibility, supporting a maximum load of 20A at 48V and standard blade fuses, making it suitable for common automotive circuits.
• Dual-LED visibility provides a bright, easy-to-read display in any light, while a built-in front work light helps illuminate tight engine bays.

How to use

Setup is simple: remove the blade fuse, insert the tester, and connect to the fuse box. This direct plug-and-test approach minimizes setup time and keeps workflow smooth, especially when working in cramped spaces.

• Plug & test – no complex configuration required, ideal for quick checks on relays, fuses, wiring, and related components.
• Rugged, portable build – impact-resistant ABS/PC housing with water resistance ensures reliable performance in workshop or mobile diagnostics.
• Battery-powered convenience – powered by a single 23A 12V battery (included) for hundreds of tests without frequent replacements.

Real‑world use cases

Use this tester to verify a blown fuse, validate a circuit after replacement, or trace intermittent issues in accessory circuits. Its lightweight form fits in any toolkit, and the clear readings help you make informed decisions during repairs or maintenance.

At a glance
