Power Circuit Probe Tester 6V-24V DC Test Light Short Circuit Tester Component Activation Electrical Tester Polarity Identify Continuity Tester with LED Light, Long Test Lead, Overload Protection

Features & details Features 【Short Circuit Following and Locating Test Light】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 Identification & Continuity Testing & Jumper Lead Operation】This power circuit probe tester can help you quickly identify positive and negative polarity of electric cables and plugs of vehicles.

When the probe tip contact to the positive electrode, the RED light on.

When the probe tip contact to the negative electrode, the GREEN light on.

It can also test for continuity and do the jumper lead operation with the assistance of its auxiliary ground lead.

【Activate and Test Components In/Out of Vehicle’s Electrical System&Poor Ground Contact Testing】Power circuit probe tester could activate components in and out of the vehicle’s electrical system, test and check the components if defective or not, or if rating current of component is higher than that of the circuit tester.

For some components, the negative terminal is required to be well grounded to cope with the flow of large currents, this circuit tester is a good tool to test their grounding.

【13FT Long Extension Cable&LED Light Prompt&Buzzer Warning&Highly Sensitive Probe&Clips with Strong Bite】The cable length of the circuit tracer is about 4m(13ft) which allows you access and test any electrical system easily.
