Ok guys, no idea what's going wrong. I replaced the F104 fuse and played a game. I could see this fuse light up when the spirit ring magnet activated but hung on there for a good while. Then tried solenoid test mode and all solenoids on this line lit the fuse like a light bulb when they activated. The only reason the fuse didn't blow was I let go of the door switch in time. What I did notice was the transformer really started to hum loudly when testing a solenoid on the line.

I tried removed the left drain magnet from the game and it wouldn't fire up. Reconnected it without the rod/core and it powered up. Just unplugged the right magnet and same thing happened. And yet my first test for the night was to unplug both of these magnets and I could power up and play a game, although the fuse still was under much stress.

Any idea on what to try or is it time for a tech? Thanks. Btw I have unplugged the game from the gpo
