The Sealey AK4013 is an integrated test light and voltmeter designed for accurate electrical diagnostics on automotive and light commercial vehicles. This dual-function diagnostic tool combines traditional circuit testing with digital voltage measurement, providing clear polarity identification through its colour-coded LCD display. The tool features a practical wire hook probe design that simplifies testing in tight spaces and behind insulation. The hook mechanism can pierce wire insulation when needed, making it easier to access circuits without stripping wires, whilst the probe can be locked out of the way for terminal testing. The LCD meter draws minimal current during testing, making it safe to use around sensitive electronic components including modern vehicle management systems. With a voltage range of 3-60V DC, the AK4013 is suitable for diagnostics across motorcycles, cars, mild hybrid vehicles, and commercial vehicles. The tool is supplied complete with a 3-metre coiled cable for extended reach and an insulated crocodile earth clamp for secure connections. A CR2032 battery is included, allowing immediate use straight from the box.
