Lisle Electrical Multi-Tester
Lisle Electrical Multi-Testers: Specialty Diagnostic Tools Built for the Shop
When it comes to automotive electrical diagnosis, having the right testing equipment isn't just a convenience — it's the difference between a quick fix and hours of guesswork. Lisle, an Iowa-based manufacturer celebrating over 120 years of continuous production, brings that same specialty-tool mindset to its line of electrical multi-testers. These aren't generic, off-the-shelf instruments — they're purpose-built tools designed with the working technician in mind.
What Sets Lisle Apart in Electrical Testing
Lisle's approach to electrical diagnostics reflects the company's broader philosophy: with more than 500 products, the company is always innovating new tools that make stubborn jobs easier and quicker. In the multi-tester category specifically, this translates to products that go beyond basic voltage checks and address real-world diagnostic challenges that mechanics face every day.
A standout example is the Lisle 64970 Parasitic Drain Tester, which provides an easy method to connect a multimeter to the vehicle electrical system to diagnose hidden battery drain, with replaceable in-line fuses to protect both the meter and tester in the event a high current source is left on. Tracking down a slow battery drain is one of the most tedious electrical jobs in any shop, and this tool is engineered to simplify that process significantly.
For technicians who need to extend the reach and versatility of their existing meters, the Lisle 82650 Multimeter Accessory Kit is a comprehensive solution. Designed to extend multimeter capabilities, it features interchangeable probes for a wide range of testing possibilities and is compatible with most multimeters and scopes with standard 4mm connectors. The kit includes 43" long 4mm banana test leads with straight and 90° connections, test probes, long back probes, safety test probes, crocodile clips, female-to-female adaptors, male-to-female adaptors, small alligator clip with male banana and slotted ring adapters, plus a roll-up storage pouch to keep leads and adapters organized.
Lisle also offers dedicated circuit testers for quick on-vehicle electrical checks. The digital circuit tester features an operating range of 3–49 volts DC to work on most vehicle electrical systems, with 360° visibility of polarity — the red light indicates positive polarity and green indicates negative polarity. This kind of thoughtful design detail is a hallmark of the Lisle engineering approach.
