【Polarity Test & Wide Applications】:When using the probe tip to test the positive and negative poles of automobile
circuits or components, the red light of the polarity indicator will light up when the positive pole is touched, and vice
versa when the negative pole is touched, the green light will light up. It can test circuit or components on cars,
pickup trucks, SUVs, motorbikes, construction vehicles and boats

【Multi-Functional Circuit Tester】: It can test polarity, continuity of car circuit, locate the short circuit, components
of car (lamp, horn, etc;) and the grounding condition. You can also repair or inspect the circuit with jumper lead operation.
With this tool in hand, you no longer have to worry about any electrical problems of car circuits.You can keep it at home
to quickly check the car's circuit and components.

【Continuity Test】: Using the probe tip and an auxiliary ground wire, the continuity test can be performed on circuits
and components of the automotive electrical system to determine if they are disconnected. If the circuit or component
passes the continuity test, the green LED lights up. Otherwise, there is a short circuit in the vehicle circuit or component.

【Quick Testing of Components】: With the power circuit probe and alligator clip, you can control the probe to output a
positive or negative voltage by pressing the button. So it can test vehicle components such as lamps offline, or to test
components by connecting them to the vehicle wiring. The automotive voltage tester also supports jumper operation,
which can jump over the original line to check or locate the short circuit.

【Grounding Test and Buzzer】: Some components require good grounding of the negative iron part for large current flowing,
and the circuit tester can check the condition of the component grounding. If the grounding is good, the buzzer
will sound and the polarity indicator will turn green, if the grounding is bad, the polarity indicator will remain red and the buzzer
will not sound. The buzzer will sound whenever the contact negative path is good.
