Review on 🛠️ Relay Buddy Pro Test Kit: Electronic Specialties 193 Black - 2.5" x 5" 12/24V Diagnostic - Shop now! by Kimoni Arenas

Great little kit for testing relays for 12 and 24 volts Yes there are other ways to test relays with a voltmeter but it is much easier just plug the relay into the correct socket, by car connect battery, push button! It tells you if the relay is good and gives you an error code if the relay is bad. I also have relay clamps that are difficult to remove to keep my hands off the relay in tight spaces and I also have an extra relay adapter for larger relays testing for cooling. Fans not included in this kit but need to be included again, there are other ways to test the relay but with this kit it's quick and easy
