This week’s feature product is an entire line of one of the most common construction components. Nails! You might be surprised to learn that there are different nails for different jobs, so I’m gonna hammer home the details. Check out the family of Construction Nails from Duchesne.


Relays, for those unaware, are little switches in a box that use electricity to turn the current on and off, and works in conjunction with your car’s computer to control everything from your lights, fans, and even locking your doors. Over the life of a car, a relay can break due to consistent use or, more commonly overheating.

Unlike a fuse, you can’t inspect a relay just by looking at it, so normally, you’d have to wire it up to the car battery, and sometimes use a multimeter to see if the relay is still functional. This Relay Tester, as the name implies, makes it super easy to test most common 4 and 5 pin relays you’ll find under the hood.

Simply plug the relay into the unit, press the test button, and wait for it to give you either a green light for good, or a red light for bad. It couldn’t be simpler! Having the ability to quickly test a relay not only saves you time, but helps you get to the root of a car problem faster as you can swiftly determine if the issue is simply a dead relay, or if it runs deeper. It’s compact size also makes it convenient to carry around or store in a tool box, and runs on just 4 AA batteries, which are included!

So, speed up your diagnostics, and save yourself time with this week’s feature product, the 12V Automotive Relay Tester from Performance Tool.
