Maybe this post from my Bon Voyage thread might help a bit, those are Ballys of very similar vintage and I would guess the chime boxes are similar. There's a pic of the chime box there that shows the solenoids and wiring pretty well.
Now having looked at this more closely, I find myself confused!!! I have brought over the pic of the Bon Voyage chime box, here it is.

I have conflicts all over the place. The schematic shows the colors for the 3 chimes as follows:
10 pt BLUE-W
100 pt O-W
1000 pt G-B
In the pic the BLU-W wire which is presumably for 10 points is the middle chime. Seems like it should be the shortest one?
The O-W wire which is presumably for 100 points is on the tallest chime.
The other solenoid has a R-W wire, not G-B. Not sure what is going on there. Error in the schematic? Someone swapped it?
The Captain Fantastic schematic shows it like this:
10 pt R-W
100 pt BLU-W
1000 pt O-W
So it should be easy to wire it up, except now I am confused as to the pairings of the solenoids and the chimes. I would have thought it would go like this but my BV is not set up that way.
10 pt shortest
100 pt middle
1000 point tallest
