The Sealey Wire/Cable Piercing Test Lead Probe Set is a professional diagnostic tool designed for automotive electrical testing, allowing technicians to test live circuits without damaging wire insulation permanently. These fully insulated test probes feature a spring-loaded clamp mechanism with a self-centring stainless steel pin that punctures through cable insulation to make contact with the conductor beneath. This design enables quick and accurate voltage readings on automotive wiring systems without the need to strip or cut cables. The probes are fitted with 4mm banana-style connectors, ensuring compatibility with most multimeters and diagnostic analysers commonly used in automotive workshops. Designed specifically for automotive applications, these piercing probes are rated for a maximum input of 50V DC, making them ideal for testing 12V and 24V vehicle electrical systems. They can accommodate cable sizes up to 3.5mm in diameter, covering most standard automotive wiring gauges. The compact and lightweight design makes them a practical addition to any mobile mechanic's toolkit or workshop diagnostic equipment.
