I found a couple of old threads related to this problem, but they don't specifically relate and not the sure answers were helpful to this issue. When I got the machine the magnets did not work, and we traced it back to a blown F7 fuse. Replaced the fuse, and the magnets both worked during test. Played a game and the new fuse was bad by the end of the game. Tried another fuse and the fuse went again. I watched the fuse during the next game and it looks like it blew after maybe the third or fourth time the magneto magnet came on during the game. Any suggestions? Thanks.
