If I run the snagger playfield magnet or orbit magnet test more than 3 or 4 times in a row either the local magnet 3A slow blow fuse or the driver board F20 3A slow blow fuse (covers both magnets) blows. Seems like it shouldn't blow ever unless there is an issue. The diodes at the magnet fuses test good and the magnet coils test good (4.5 - 4.5 ohms). Seems like the fuse value is low, similar to the ring magnet in Lord of the Rings that needs a 5A fuse instead of the factory spec'd 4A. I'm thinking of putting 4A fuses instead of the 3A in all three locations. Thoughts? Any troubleshooting tips?
