ems04: This is exactly what the tool trucks sell and it’s way cheaper on here. I bought one and couldn’t be happier, makes testing breakers easy

Bob_F: My mechanic turned me on to the Relay Buddy. Loaned me his to diagnose a bad relay causing a starter problem. Saved me a bundle! So I bought my own, to chase down all the remaining gremlins!

Philip Elder: It's great to pop a relay on and run the test to make sure it's not fading or blown.

Need adapters for the small GM based relays as well as the large bladed ones. Keep that in mind when purchasing to make sure that any needed relay adapters are purchased.

David Moorhead: Got this in an effort to overhaul an older Honda with problematic electrical issues. It's not rocket science to use, you just count the number of pins on your relay which is going to be 4 or 5, set the switch and hook up to battery. The tool bounces the relay back and forth for a little while and returns either a good or bad LED. I have bought many relays over the years because all troubleshooting *seemed* to point to a bad relay, but sometimes it wasn't the issue at all. I'll never have to buy another relay I didn't actually need, hopefully. So far, so good. It's a very simple device that does what I need it to.

Jonathan: Just received my relay buddy. Works ok. I tested a 4 pin relay that I suspected of being defective and it confirmed it. The relay buddy cycled 3 times and stopped with the red light on. Easy to use. The only thing that I am not happy with is that the green light isn't working. I tried a couple of new Bosch 4 and 5 pin relays and it would do the cycle but no green would come on. not sure what the issue is. I looked at the instructions and made sure the relay schematic matched the instructions. Hopefully mine isn't a lemon.
