I had my original and a replacement fail after a game or two each. Asked for another replacement a couple times, but never got one. My magent has literally worked for a total of 3 or 4 games and I've owned the game since January. I've given up for now. They clearly don't have a solution at JJP which is mind-boggling.

The fuse (or switch) pops when the heat exceeds its limit. If you mount it so it's not alongside the coil, it will be useless, as it will never heat up even if the coil is locked on. But at least the damned magnet will work!

If they can't get the hardware to work (and they can't for some damned reason), they should allow the software to compensate for it, maybe a "disable magnet" setting that allows the player to collect the extra ball or "shoot the top lanes" shots needed in a song with an orbit shot.
