The backbox roulette wheel never spins. The relay that runs it clicks at the right time.
Roulette wheel won't spin though its relay clicks: wheel seized by old grease
Cause: The wheel was mechanically stuck: old grease had gummed up and the motor could not turn it.
Checks
- With the game off, try turning the wheel by hand from underneath. It should turn freely.
- If it turns, clean the wiper contacts under the wheel and check the motor circuit fuse and resistor.
Fix
- Work the wheel by hand until the old grease breaks free.
- Then strip, clean and lightly re-lubricate the wheel bearing so it does not seize again.
