When I have a Fuse blowing issue, it turned out to be a open/close switch where both sides were closed. Power was being drawn to both sides, that cause too much draw so fuse would blow. I would check the circuits that are activated when the motor is in the position that blows the fuse.

Since you were working on the score reels I would check the relays in the back box first.

The outhole relay and game relay are two examples in this curcuit.

Quoted from valveamp:

However, after a few plays, the ball count started counting all the way up to 10 on a new game and the score motor would continue to run for several seconds before stopping. After a few occurrences of this, the fuse blew for the first time.

Is this still happening? The machine might think you are in a reward mode and trying to give credits or extra balls. you may have to unplug this adj. and see why it is being continuous triggered.
