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 Ken Pinell

This is a professional performance probe with many options. The voltmeter is accurate and the probe itself is very sharp and sharp for getting into some of those bundles packed with wires. The relay test function is very practical. The ability to switch modes to test the fuel solenoid is a huge plus. The probe is made of hard quality plastic and the buttons feel solid too. I only wish it came with a case to store it as the box it came in was well packaged and I use it as a case to keep everything together. The cables are a good gauge and the battery clips are better than most charging cables. The display is bright and readable in daylight, but shade certainly improves visibility a lot. The end of the probe has a light to help you see in tight spaces and an audible beep to help you check for a positive or negative result. tells you what polarity the wire under test is, so you don't have to keep looking at the indicators.
