GBC 4250 Blows 1A 250V SloBlo under right cover?

This machine was gifted to my church from a local school. They said they took it to a repair shop to get it fixed and the guys there told them it couldn't be fixed and they should buy a new one for $5200. Which they did. Since the one they bought was NOT a GBC, it wreaks of a dishonest service department. The reverse button was sticking in the on position, but I was able to disassemble, clean and restore it to working order, but it still pops that 1A sloblo. Anyone have a wiring diagram? Not sure, but I think that the Triac on the right side is the likely culprit. They are cheap anyways. (about $12 to $15) I just need to track any and all culprits and verify that the previous repair shop didn't do and "creative" fixes while they had it (ie swapping wires so that the fuse would blow every time)
