A coil on my Jokerz machine recently burnt up and smoked everywhere. Looking further inside the machine I see another burnt up coil that has been disconnected. Does anyone know what causes coils to burn up like this? Is it strange that multiple coils are burning up? Will simply popping a new one in fix the issue or does the problem lie somewhere on the board like a transistor? Thanks!

Okay I finally got around to checking the transistors. I tested all of them and they all tested fine...

Okay I just looked and not one of the coils in the Jokerz has a diode on it. Was it made this way or did someone really replace every coil incorrectly? Thanks!

Thanks guys. I'm replacing the relay because I did it incorrectly before and clay's guide says that makes many coils stop working like I have.
