As part of my project vehicle, I found this very helpful in testing relays. As far as relay testing goes, I like how easy it is to use, as well as how accurate. The price is worth the purchase, and I would recommend it.

In the event you were never taught how to read the diagrams on the side of a relay or if (like me) you have no memory of the details of troubleshooting relays, this inexpensive item is the perfect solution. I'd say it's a simple transaction. It's just a matter of attaching the battery clamps to give it power, switching the unit to 4 or 5 pin reading and matching your relay's legs to the correct arrangement, then plugging in the relay. I expected that my relay would begin testing before I pressed the 'test' button and flash a green light and sound an audible click, indicating that it was a good relay. A star was taken off for the picture showing a carrying case, but all I received was a No matter how you look at it, it is still a useful thing to have.

Worked like a charm. It is highly recommended that you read this book. With the price you get it right, it's worth adding to your toolbox to always have it handy. On my starter relay that had a 4 pin connection, I used this one, and it worked. A good meter would provide accurate readings. You can use it in just a few minutes and it's very easy to do. Adding this to my toolkit will be very helpful.

The tool came in very handy for testing my wife's relays and battery on her Jeep Wrangler, which had an electrical issue. We ended up needing a new battery, but it was great to have that problem confirmed before spending a lot of money. I really enjoyed the ease of use and accuracy of this tool.
