There may be a timing requirement in the code, too, requiring the spinner and the magnet to trip within microseconds of each other. So if you're testing manually with the glass off, make sure to trip both switches as close together as possible. For example, flip the spinner with your left hand and feed the ball to the ring with your right hand at approximately the same time.

Switch #42 (Inner Loop) doesn't have anything to do with the final shot on DTR. Switch #42 registers a successful Gandolf shot above the playfield at the very end (top) of the inner orbit, just above and to the left of the O-R-C rollover switches.

The only switches that matter for the final shot on DTR are #52 (Spinner), #47 (Ring Made), and #48 (Back Trough), so if Switch #47 and Switch #48 are working, you need to focus on Switch #52 (Spinner).

Your Spinner switch isn't wired correctly. If the machine is in Switch Test mode, when you spin the Spinner by hand, the DMD should confirm that Switch #52 (Spinner) is activated, NOT Switch #42 (Inner Loop).

Reach down and pull up on the Inner Loop switch, and see if the DMD shows Switch #42 (Inner Loop) is activating? If it's another switch (e.g., #52), then something probably got cross-wired during prior maintenance.

Congrats! Now go destroy that ring!
