Meagkka Power Circuit Probe Tester, 6-24V Automotive Circuit Tester, Auto Electrical System Test Tool DC Digital Voltage Short Finder Car Truck Circuit Test Pen
Free ShippingMain highlights- 【Portable Multifunctional Probe Tester】The circuit tester is suitable for diagnostic in all 6V to 24V DC vehicle electrical systems. It can check switches, relays and the on-off of diodes, fuses and circuits, which can help you reduce diagnostic time in automotive electrical systems. In most cases, short circuit or instant overload of component will lead to blown fuse or circuit breaker tripping.This probe tester can assist you tracing problem wires and locating breaking points.
- 【Polarity Test and Continuity Test】The tester is made of insulating material and high-quality stainless steel, which can help you quickly identify the positive and negative polarity of the vehicle cable and plug. When the tester touches the positive pole, the LED should be red; when it touches the negative pole, the LED should be GREEN. The electric circuit tester is also used to check the continuity of switches, relays, diodes, fuses, and circuits.
- 【Easy Operation Circuit Tester】Unroll the leads. Clamp the red clip of the power circuit probe tester to the positive terminal of the vehicle's battery. Clamp the black clip to the negative terminal of the vehicle's battery. After a simple hook-up of the circuit tracer to the vehicle's battery, automotive technician can conduct a positive or negative battery current to the tip by rocking the power switch forward or backward.
- 【Component Activation and Testing】For professionals or car enthusiasts, this continuity tester is a great tool. The automotive short circuit tester can activate the components in/out of the vehicle's electrical system. The LED indicator and buzzer prompt can easily test and check whether the components are defective, or whether the rated current of the component is higher than the rated current of the tester.
- 【Automotive Circuit Tester for Grounding Test】The design of the circuit breaker finder is perfectly designed and feels comfortable. It is equipped with a 4M extended detection line, covering the front to the rear of the vehicle and easily detecting the entire vehicle circuit system.
