Starting a 2-player game lights the right player count, but after player 2 drains the game moves on to player 3 and then 4, and hangs on player 4.
Two-player game runs on to players 3 and 4: hidden broken wire on the coin unit
Cause: A wire on the coin unit (which remembers how many players are in the game) had broken inside its cloth insulation, so it looked fine.
Checks
- Clean the coin unit and player unit steppers.
- Gently tug every wire on the coin unit while watching for one that stretches or parts inside the insulation.
Fix
- Repair the broken wire.
EM games carry line voltage at the cord, transformer and switch; unplug before working inside.
