Lisle 28800 Digital Test Light with Load Tester 3-30V DC

The Lisle 28800 is a dual-polarity digital test light with integrated load testing capability, designed for 3-30 volts DC automotive electrical diagnostics. This advanced diagnostic tool goes beyond standard test lights by applying an 800mA load at 12V DC to reveal voltage drop issues that indicate hidden circuit problems.

Key Features:

• Digital voltage display shows real-time readings from 3-30V DC with dual polarity detection
• Built-in load tester applies 800mA load at 12V DC at the push of a button
• Instant voltage drop readings help identify corrosion, resistance, and faulty connections
• Functions as both a standard test light and diagnostic load tester
• 48-inch heavy-duty cord with secure alligator clamp for reliable ground connection
• Easy push-button operation to toggle between standard and load testing modes

This tool is ideal for diagnosing charging system problems, testing battery condition under load, and identifying high-resistance connections in automotive circuits. The digital display provides precise voltage readings, while the load testing function reveals problems that won't show up with a standard test light or multimeter alone.

Important Safety Notes: Not computer-safe when load is applied. Do not use on airbag circuits or sensitive electronic systems when using the load testing function.
