Can someone school me on adjusting Bally/Midway power brick lugs for good AC voltage?

I'm trying to bring a dead Arch Rivals back to life. The 3A fuse on the transformer/power brick kept blowing, turns out the main pcb must be shorted, because I unplugged it and the fuse stopped blowing.

The monitor is also dead, so I measured the AC coming from the transformer and it's at around 134vac. Is that likely to overload a typical monitor? (going to use a wg7000 series)

I know that one can move the wires on the iso transformer to different lugs to get the voltage down closer to 120. Should I bother?

Can someone help me out on this? I have the Arch Rivals operator's manual, but schematics are not my strong suit. Thanks, Marc

It is not adjustable.

Arch Rivals is a weird game, it requires the wiring to be exact or the fuse will blow. The HOT side must follow the HOT path, and the same for the Neutral side. Had this problem and thought I had a bad boardset, now I have 2 working Arch Rival boardsets.
