After a ball drains the bonus counts down, but the game never advances to the next player or ball and stays on player 1, ball 1.
Game stuck on player 1, ball 1: broken wire on the ball index relay
Cause: The ball index relay was not pulling in at the end of the ball. One wire to it had broken off at its solder joint, though it looked connected.
Checks
- Watch the ball index relay when a ball drains; it should pull in.
- Check the outhole switch closes and fires the ball return.
- Gently tug each wire on the relay and its switch stacks to find one that is broken off.
Fix
- Resolder the broken wire to the relay.
EM games have line voltage (120 V) at the transformer and power switch; unplug the game before working on wiring.
