Simplified Power Circuit Tester for 6V-24V DC with LED, Overload Protection

The circuit tester is designed for use with 6-24V DC vehicle electrical systems. It features an operating voltage range of 6-24V DC, and must be connected to the vehicle battery before use.

An overload protection function is included, which will automatically disconnect the current if it exceeds 7A. The tester has a weight of 200g and is constructed of plastic and stainless steel materials. The cable length is 4m / 157.5 inches, with an overall item length of 225mm / 8.85 inches and width of 30mm / 1.18 inches.

When a circuit breaker trip is detected, the tester will sound a prompt to indicate a short circuit problem. It will then automatically reset within 3-5 seconds, turning off the prompt sound so the user can retest or move to another location.

The package includes 1 circuit tester, 1 probe tip, 2 clips, and 1 user manual in English.

This circuit tester is suitable for diagnostic use in all 6V to 24V DC vehicle electrical systems. It can be used to check switches, relays, diodes, fuses and circuits, helping to reduce diagnostic time in automotive electrical systems. Short circuits or component overloads often result in blown fuses or tripped circuit breakers, which this tester can assist in tracing and locating.

The tester can quickly identify the positive and negative polarity of vehicle electrical cables and plugs. When the probe tip contacts the positive electrode, a red light will illuminate; when it contacts the negative electrode, a green light will turn on. It also enables continuity testing and jumper lead operation with the help of the auxiliary ground lead.

The tester can activate, test and check components both in and out of the vehicle's electrical system, determining if they are defective or if their current rating exceeds that of the tester. For components requiring a well-grounded negative terminal to accommodate high currents, this tester is a useful tool for ground contact testing.

The 13ft long extension cable allows easy access and testing of any electrical system. LED indicators and a buzzer provide clear problem identification, while the advanced, highly sensitive probe and strong-grip clips deliver quick, accurate detection.

Before testing, the tester can perform a quick self-test to ensure proper functioning. Overload protection will automatically disconnect the current if it exceeds 7A, and provide a buzzer prompt. Poor ground contacts can be tested directly.

Note that this tester is only suitable for 6-24V DC systems, and should not be used on 110/220V AC voltage.

When a circuit breaker trip is detected, the tester will sound a prompt, then automatically reset within 3-5 seconds to allow retesting or moving to another location.

The circuit tester is easy to operate - simply unroll the leads, clamp the red clip to the positive battery terminal and the black clip to the negative, then use the power switch to conduct positive or negative current to the tip.
