Vehicle Circuit Tester — Electric Auto Tester Quick summary A compact, portable vehicle circuit tester designed to rapidly locate faults in automotive electrical systems. Built from durable materials and equipped with a spring-wire probe, it’s suitable for professional mechanics and DIY enthusiasts for routine diagnostics and on-the-road troubleshooting. Key benefits — why you need it - Fast fault finding: The spring-wire probe and voltage-sensitive tip let you quickly check continuity, voltage presence and simple circuit faults without disassembling components. - Durable build: Constructed from polycarbonate (PC), iron, plastic and rubber for resistance to damage and wear, giving reliable service in workshop or field use. - Portable and convenient: Small, lightweight design makes it easy to carry in a toolbox, glove compartment or service bag so you can test circuits wherever needed. - Versatile application: Functions as an electrical/light tester and a general circuit tester for a wide range of automotive electrical checks. Features and attributes - Function: Electric vehicle circuit tester capable of detecting voltage, continuity and basic circuit faults; suitable as a light tester and voltage-sensitivity tester. - Probe: Spring-wire probe for flexible, reliable contact with terminals, connectors and wiring. - Materials: Housing and components made from PC (polycarbonate), iron, plastic and rubber for strength and impact resistance. - Size & portability: Compact form factor for easy storage and handheld use during inspections and repairs. - Intended use: Designed specifically for motor vehicle (KFZ) electrical systems; ideal for mechanics and home users working on cars and light vehicles. Practical use scenarios - Workshop diagnostics: Quickly identify a blown fuse, damaged connector or interrupted wire while troubleshooting headlights, taillights or interior lighting. - Mobile roadside repair: Carry in the vehicle to check battery connections, starter circuits or charging system presence after jump-starting or a breakdown. - DIY maintenance: Test wiring and switches after component replacements (bulbs, sensors, switches) to confirm correct voltage and continuity before reassembly. What it solves - Eliminates guesswork by giving immediate indication of voltage/presence and circuit continuity. - Reduces time spent disassembling panels and components to find simple electrical faults. - Provides a durable, portable tool that withstands workshop conditions and everyday handling. Compatibility and suitability - Suitable for standard automotive wiring and electrical components found in cars and light vehicles. - Recommended for professional mechanics, technicians and DIY users who need a reliable, easy-to-use circuit and light tester. Note: Use appropriate safety precautions when testing live circuits and follow vehicle manufacturer guidance.
