The KINGBOLEN ECT200 is a professional 12V/24V automotive circuit tester designed for fast and accurate electrical system diagnostics. Combining voltage testing, polarity detection, continuity testing, ground testing, component activation, and trailer light diagnostics in one compact tool, it helps technicians and advanced DIY users quickly identify electrical faults across a wide range of vehicles.

Real-Time Voltage & Polarity Detection

The ECT200 provides real-time DC voltage measurement within an 8V–32V operating range. A clear digital display, combined with dual-color LED indicators, allows you to quickly identify circuit voltage and polarity, making it easier to verify power supply, inspect electrical circuits, and locate voltage-related issues.

Continuity & Ground Testing

Quickly verify circuit continuity and ground integrity with built-in visual and audible indicators. The ECT200 helps identify open circuits, poor ground connections, and wiring faults, making it suitable for diagnosing switches, connectors, wiring harnesses, and electrical accessories without requiring multiple test tools.

Component Activation

The ECT200 features Power Probe component activation, allowing you to apply battery voltage or ground to compatible 12V/24V components for functional testing. This makes it easy to verify the operation of components such as cooling fans, headlights, relays, blower motors, solenoids, and other electrical devices before replacement.

Always follow the vehicle manufacturer's service procedures when performing component activation tests.

Trailer Light Diagnostics

Designed with trailer maintenance in mind, the ECT200 includes a dedicated Trailer Light Test function for quickly checking trailer lighting circuits. It helps verify the operation of tail lights, brake lights, turn signals, and related wiring, making it suitable for trailers, RVs, trucks, and marine applications.

LED Work Lights & Audible Feedback

Integrated dual LED work lights improve visibility when working in low-light areas such as engine compartments and under dashboards. An integrated buzzer provides audible feedback during testing, allowing users to confirm test results quickly without constantly watching the display.

16.5 FT Extended Test Lead

The ECT200 includes a 16.5-foot heavy-duty cable, providing convenient access around passenger vehicles, pickup trucks, SUVs, trailers, and commercial vehicles without repositioning the power connection. The precision probe is designed for accurate contact with common automotive electrical connectors during routine diagnostics.

Built-In Circuit Protection

For added safety, the ECT200 incorporates reverse polarity protection and automatic overload protection. It supports component activation with a maximum output current of 8A, automatically disconnecting the output when excessive current is detected to help protect both the tester and the vehicle's electrical system.

Wide Vehicle Compatibility

Compatible with 12V and 24V DC electrical systems, the ECT200 is suitable for diagnosing passenger cars, SUVs, pickup trucks, commercial vehicles, motorcycles, RVs, trailers, and marine equipment. It is an ideal tool for automotive repair shops, mobile technicians, fleet maintenance, and experienced DIY users.
