I'm pretty new to EM's and am now officially stumped. I recently picked up a Mars Trek that was playing good except for two issue. One was the player 3 10K real wasn't resetting and the 1 to 4 can play lights weren't working. I fixed the 10K real as it was just sticky. Put a new sleeve in the coil and cleaned up all the pivot points. I fixed the other lights as well as that leaf on the coin wheel wasn't touching the board.

I started a game and played through ball 1 of players 1 and 2. With player three once I got to 100K I blew a fuse. Started looking at the things I worked on and nothing seems out of the ordinary plus it was the 100K real that had it happen. Checked the gaps on everything and everything look right.

Here's the kicker. If I manually move some of the score reals. When I go to start a game, it goes through and resets all the scores to Zero and then it blows the fuse again. I hear a buzz sound right when it blows. Can anyone please point me in the right direction on what to check next and how to check it?

The fuze that keeps blowing is the one in green below. Full schematics are here - https://www.ipdb.org/files/1550/Sonic_1977_Mars_Trek_Schematic_Diagram_continuous.pdf
