Looking at the schematic it looks like there are different switches on the Wheel score has two sections on the schematic. One to manage the bonus/double bonus/spinner values. The other manages the scoring.
I have added the scoring section. Zero on the wheel unit matches the 5000 bonus opposite the spinner lites and goes clockwise around the wheel.
Points scored at each position:
0. 5000 (following the green path)
1. 500 - green
2. 5000 - green
3. 3000 - blue
4. 500 - green
5. 500 - green
6. 500 - green
7. 500 - green
8. 500 - green
9. 3000 - Blue
For the 500/5000 point issue I would check the following (highlighted in green):
1. Switch on 2B Wire color: Yellow (30) and Yellow-Brown(38) is clean and making good contact (Recommend testing with a continuity meter).
2. Wheel score Relay switch Yellow-Brown (38) and Green-Red (41)
3. The Wheel wiper finger(s) is making good contact Green-Red (41) 1000 pt Brown-Red (81) and 100 points Gray(90)
4. ensure the wiper finger is centered on the rivet. And both are clean and making good contact.
4. While checking the switches/wipers also check for broken wires/cold solder joints.
5. Check Continuity from the motor switch to wheel score relay
6. Check Continuity from the wheel score relay to 100/1000 pt wires. (While the wiper finger is on the proper rivet).
7. watch the Wheel score relay to see if it only pulses vs hold while the motor spins.
(repeat for the blue section if required)
Note: the 500 & advance relay is NOT triggered
