Review on GODIAG GT101 Power Circuit Probe Tester Kit, Automotive Electrical System Test Tool for 6V - 40V DC Short Finder, Relay Fuse Tester, Diode Resistance Check - Ideal for Cars, Trucks, and Motorcycles by William Mistretta

GT101 Automotive Power Probe Tester with Case, 6V 40V Automotive Electrical Test Tool Kit with Current Detect Short & Open Finder This tool has everything we needed and more! The same day it arrived my husband used it to diagnose an ongoing problem he was having with our Peterbilt 379. Since he didn't have time to drive to the shop, this tool was a lifesaver. The long cable made it possible to reach any place, even on a large commercial vehicle. It's very easy to use and comes with well-written instructions that guide people unfamiliar with using the tool through the entire process. The instrument makes a solid impression and has a good weight. I would have preferred a hard case, but the soft case keeps everything in one place. All in all this is a very good tool and it works great!
