I need help troubleshooting my Olympia Las Vegas machine. The machine will not spin. Everything seems to light up, fuse good etc. I think it may be linked to LED#7, which is on all the time. Does anyone know what input it is tied to? Possibly the Bet button?

I figured out the other LEDs as follows (which all seem to work):
1 Reel sensor 2
2 Reel sensor 3
3 Stop button 3
4 Reel sensor 1
5 Stop button 1
6 Stop button 2
7 ???
8 Spin Knob
9 Token sensor
10 Max Bet
11 Token sensor
