The glider craft needs 3 switches to works.
SW30 activate Sol.23 for move craft forward. Locate back of the glider over the playfield (pics 1 and 2)
SW21 activate Sol.22 for move craft left to right. Locate under the playfield (pics 3 an 4)
The third switch is SWA2 activate Sol.15 that is used to know if the pyramid is open or not. If it is open, the pinball can launch the forward moves of the glider. The switch locate back of the glider is used to pull down the pyramid at the end of the sequence.
After 25 years of intensive use, the right and left motors of my Stargate brokes and Gottlieb have never put fuses on those motors to prevent PCB burns and A3 transistor burns. So I recommend you to add fuses on those motors. I put 7A fuses but I think it is too big...need to recalculate it when I finished my playfield restoration.
Good luck in your restauration
