About this item

• Car Circuit Tester: This professional 12 volt test light is applicable to the diagnosis of electrical systems of various vehicles such as cars, motorcycles and trucks within the DC voltage range of 6-24V. Powerful in function, it supports various experiments such as circuit polarity testing, continuity, short-circuit tracking, component activation, and grounding test, making complex circuit problems nowhere to hide.
• Circuit Positive & Negative Detection: The metal probe at the front end of the power circuit probe tester can quickly identify the charge and polarity of each unknown contact point on the car circuit. Quickly identify the current state of the car circuit and ensure the safety. A red indicator light indicates a positive charge , and a green light indicates a negative charge -."
• Continuity Testing: The electrical tester continuous testing can be used to check whether there are any open circuits or poor contact faults in automotive components, such as whether the fuse has blown, and whether the connection of switches and relays is good. The test has sufficient safety and will not cause any damage to sensitive components (such as ECU, sensors, etc.).
• Component Activation: This auto circuit tester can be connected to a circuit to quickly control or activate specific components, such as starters, fuel pumps, cooling fans, headlights, blowers, etc. When defects are found in the components during the inspection process or the rated current of the parts is higher than that of the vehicle test light, a buzzer will sound as a prompt.
• Safety & Toughness Structural: The 12 voltage test pen shape is fluent, accord with human body engineering design. It's surface adopt cutting-edge ABS material, very soft and sweat-absorbent! The edge of the handle is designed to fit perfectly in the palm of the hand, so it can be easily held and not easily slipped off. The tester is also equipped with a 4 m long cable, which can easily test the whole vehicle range of circuits.

Short Circuit Track

Use the metal probe of the circuit tester to check the circuit surface point by point.

When the fault point is found, the indicator light will light up

The analog ECU signal activates the relay, activates the vehicle lights, motors, etc. to achieve dynamic diagnosis(not recommended to test ABS sensor precision components in the car to avoid magnetization damage)
