I was alarmed when our sprinkler system suddenly stopped working. Some online research suggested it might be the fuse. Since I didn't know it had a fuse, and I've been running the sprinkler system for over 10 years, I figured it was worth a try. I popped one of these in, and our system immediately came to life. I doubt I will need the rest in the package, but I'll hang on to them in case there are other things I have with hidden fuses!
