Key features

• •【Function】 Continuity tester for testing components inside and outside the vehicle electrical system: This electrical tester can be used to test and activate components inside and outside the vehicle electrical system, testing voltage polarity, relays and diodes, fuses and circuit continuity, checking lights, checking motors, Track and locate short circuits, test for poor grounding, test cable and plug polarity, measure 6V to 24V DC voltage, etc.
• •【Application】 1 Clamp the red clip on the positive pole of the car battery, 2 Clamp the black clip on the negative pole of the car battery, 3 Connect the car probe to the bad point of 6-24V DC. You can conduct positive and negative battery currents to the probe by shaking the power switch forward or backward. The cable length is about 4m. The device has short-circuit protection, when the current exceeds 7A, the device will automatically cut off the current.
• •【Short Circuit Tracking and Locating】 The auto electrical tester uses advanced high-sensitivity probes to provide you with fast and accurate detection. Using the continuity tester can save a lot of time to troubleshoot the car wiring circuit, and quickly and accurately find the faulty wire and its fault point.
• •【Wide Application】This circuit probe tester is suitable for of all 6V to 24V automotive electrical systems which works well on cars, trucks, boats, trailers, and motorcycles.(Note: Do not use under AC voltage.)
• •【Remind】 Do not use this item near explosive gas, vapor or dust. When pressing the power switch (Note: or shaking), the battery current will be directly conducted to the pen tip, which may cause Sparks can be caused when touching the ground or certain circuits. Do not use the device under 11o/220V indoor current, only for DC6~24V system。There are detailed instructions in the product box, please refer to the operation.
