KINGBOLEN ECT200 Automotive Electrical Circuit Tester, 12V 24V Car Voltage Test Power Probe Tester, Component Activation, Continuity Test, Trailer Light Tester, Short Circuit Finder, 16.5FT Cable








Key features
- •【Practical Automotive Circuit Tester】 KINGBOLEN ECT200 can quickly detect short circuits and broken wires in vehicle electrical system components. It is multifunctional, including Voltage Testing/Component Activation(activating headlights, fans, etc.)/Continuity Testing/Ground detection/tracking and Short Circuit/Positive and Negative pole detection and Diode detection. This tool makes electrical troubleshooting easier. It is very easy to use, even if you are not a professional mechanic.
- •【Dual LED Light Design】 Powered by the car battery, the bright LED lights ensure visibility in small spaces, which is really helpful when working under the dashboard. It can quickly check the power, grounding, and conductivity of any circuit. LED lights can easily show if there is voltage present. If you are doing any kind of automotive electrical work, the KINGBOLEN ECT200 circuit tester is essential and can save you a lot of time and frustration.
- •【Component Activation & Continuity Test】 The activation function can be used to activate components such as the starter fuel pump, solenoid valve, blower, cooling fan, headlights, etc. By using probe tips and auxiliary grounding wires, continuity testing can be performed on wires and components disconnected from the vehicle's electrical system. If the continuity test passes, the green display light will light up.
- •【Ground Test & Trailer Light Test】 Use a probe to make contact with the negative terminal of the component. When the ground test passes, the green light will light up. By using grounding clamps, it is possible to test the conductivity between electrical system points, such as an unconnected trailer. Connect the auxiliary grounding wire, connect the probe to the socket of the trailer sensor, and then press the (+) button to test the function and direction of the trailer light.
- •【Easy To Use】 With digital display making reading results simple, it's very easy to use. Sturdy construction quality, compact enough to fit in a toolkit. Backlit LED display screen and buzzer can quickly provide results during the testing process, making it easy to diagnose electrical problems. Red light indicates positive pole, green light indicates negative pole. It can effectively test 12V and 24V vehicles, making it easier to use and read than doing the same thing with a multimeter.
- •【Powerful Compatibility】 Equipped with a 16.5FT cable that covers the front and rear of the vehicle, it is convenient for long-distance use and can easily test the entire vehicle's electrical system. The probe is very sharp and can pierce through insulation layers or pass over sliding connectors, determining wire loom pins, and accurately inserting smaller 2mm to 4mm vehicle connectors. Well made, very easy to use, compatible with 12V 24V cars, trucks, trailers, pickups, boats, and more.
