I'm having a weird problem with a Dirty Harry machine. The game starts up just fine - no credit dot, then at a certain, random point during gameplay the flippers stop working, the game serves all the balls into the shooter lane, and a bunch of different coils start randomly firing. Then, when it all calms down, it says to check Fuses 114 and 115. I replaced both of them with brand new ones, restart the game, and the same thing keeps happening. I'm mystified...

kinda sounds like its re setting. check the +5V on the CPU and the power driver board and if its below 4.92 you need to do the +5v mod

also id check your ball trough opto switches are working under the switch settings in test mode
