Kingbolen ECT200 Car Circuit Tester is a versatile 12V/24V power probe and automotive circuit tester designed to simplify complex electrical troubleshooting. It acts as a digital multimeter, test light, and component activator in a single handheld tool, allowing you to trace wires and test circuits without needing multiple instruments. Key Diagnostic Capabilities 6-Function Versatility: Performs voltage testing, polarity detection, continuity checks, ground testing, short circuit tracing, and component activation. Integrated Component Activation: Allows you to instantly power up components like fuel pumps, starter motors, cooling fans, and headlights by injecting battery power or ground directly through the probe. Digital Voltage Display: Features a backlit LED screen that shows real-time voltage levels from 0V to 80V with high precision. Instant Polarity Identification: Uses dual-color LEDs and a buzzer: Red LED: Indicates a positive ( ) circuit. Green LED Buzzer: Indicates a negative (-) ground circuit. Long-Distance Reach: Equipped with a 16.5-foot (5-meter) cable, allowing you to test from the battery all the way to the rear of the vehicle, including trailer lights. Technical Specifications Feature Specification Input Voltage 8V – 32V (Powered by vehicle battery) Test Voltage Range 0V – 80V Activation Current 0A – 8A (Maximum output) Circuit Protection Built-in 8A resettable circuit breaker Display High-definition backlit LED screen Operating Temp 0°C to 60°C (32°F to 140°F) Professional Use Cases Finding Short Circuits: Trace a circuit by removing a blown fuse and probing the contacts. If the green LED lights up, you have confirmed the wire is shorted to ground. Bench Testing: Power and test bulbs or relays directly on your workbench by using the probe to provide positive voltage or ground. Trailer Light Testing: Connect the auxiliary ground clamp to the trailer ground and use the probe to verify the function of each pin on the trailer socket. Continuity Checks: Use the probe and auxiliary ground wire to test if a wire or component is broken without removing it from the vehicle. How to Locate a Short Circuit with the ECT200 Remove the Blown Fuse: Connect the ECT200 to the battery and touch the probe to the load side of the fuse terminal. Inject Power: If the breaker trips immediately, the short is currently active. Trace the Loom: Move along the wire harness. If you find a point where the short disappears or the tool indicates a “Ground” where there should be “Open,” you have found your pinched wire.
