5-90V Digital LED Circuit Tester: A Comprehensive Tool for Automotive & Electrical Diagnostics

5-90V Digital LED Circuit Tester: Comprehensive Automotive & Electrical Diagnostics Tool

Expanded Voltage Capacity & Extensive Use

The 5-90V Digital LED Circuit Tester offers an enhanced testing range of 5V-120V, allowing for versatile diagnostics across a wide range of vehicles, including cars, trucks, SUVs, and boats. This tester is perfect for quickly assessing car battery voltage and diagnosing common issues. It also functions as an alternator tester, making it ideal for checking charging systems and ensuring that your vehicle’s electrical system is operating efficiently. Additionally, this tester is highly effective in inspecting the integrity of various electrical components like headlights, taillights, fuse connections, and more.

LED Digital Display for Accurate Readouts

Equipped with an LED digital voltage display, this circuit tester provides clear and accurate voltage readings. Unlike LCD lights, which can be difficult to read under bright conditions, LED lights remain easily visible regardless of ambient light, making them perfect for both daytime and low-light environments. Whether you’re working in bright sunlight or dark corners, you’ll always get precise measurements without any hassle.

Flexible Spring Wire & Large Alligator Clip

This automotive circuit tester features a 90.5-inch spring wire, providing added flexibility during testing. The long cable design allows you to move around the vehicle comfortably, ensuring you can reach tight or difficult areas. The wire’s anti-bending tail design also prevents bad connections, improving overall reliability. Coupled with a large alligator clip, the tester facilitates one-handed operation, making it easier and more efficient when checking car battery capacity and other electrical components.

Bidirectional Indicating Light for Polarity Detection

A unique feature of this tester is its bidirectional indicating light. The circuit board has a built-in LED indicator to show the polarity of the circuit. A red light signifies positive polarity, while a green light signals negative polarity. This functionality allows for easier and safer operation, as you can attach the alligator clip to either the positive or negative ground and use the probe to check the other side.

Wide Range of Applications

This auto electric tester pen is an essential tool for diagnosing electrical systems in a variety of vehicles. The sharp, long probe is designed to pierce wires and access narrow spaces, making it perfect for checking automotive components such as:

• Headlights
• Taillights
• Turn signal circuits
• Faulty sockets and connections
• Fuses
• Broken wires

It’s an indispensable tool for both professional mechanics and DIY car enthusiasts, ensuring quick and efficient diagnostics for daily use.
