24550 Computer safe circuit tester

Modern Harleys are packed with sensitive electronics, and using an old-school test light can sometimes do more harm than good. This Lisle computer-safe circuit tester is designed for 3V to 28V systems and draws less than 21 mA at 12V DC, ensuring you will not fry any delicate modules while troubleshooting. It features a clear red light for positive polarity and a green light for negative, making electrical diagnostics straightforward and fast. This universal tool is essential for tracking down wiring gremlins without risking damage to the bike's computer system. If the bulb ever goes, you can easily swap it out with a replacement to keep your diagnostic kit ready for the next job.
