Digital Circuit Tester Automotive 3 V-48 V Voltage Range with LED Display

Find car electrical faults without hours of guesswork!

A digital circuit tester helps you pinpoint electrical faults in a car, van, boat or similar vehicle without hours of trial and error. It measures from 3 V to 48 V, displays readings on a bright LED digital screen, and connects via a 178 cm spring cable with a large crocodile clip, with built-in red and green lights showing polarity instantly. You get a clear voltage reading at any contact point, so you can identify the fault and get back on the road faster.

Why is this Digital Circuit Tester perfect for you?

• Extended voltage detection: Measures precisely across a 3 V to 48 V range, so it works on cars, trucks, boats and SUVs alike.
• LED digital display: Shows voltage readings clearly in any light, so you can read results indoors, outdoors or under the bonnet.
• 178 cm spring cable with crocodile clip: Stretches without kinking and grips firmly onto various contacts, letting you test hard-to-reach points single-handed.
• Bidirectional polarity indicator: Lights up red for positive and green for negative, so you confirm polarity without guesswork.
