Each time 100 points score, the thousands reel also advances.
Every hundred-point score also adds a thousand
Cause: The carry switch on the hundreds score unit, which should close only when the unit is at 9, is closed all the time.
Checks
- With the game off, slide out the score units and step the unit by hand, watching which switch closes only at position 9.
- Compare its gap with the same switch on the tens unit.
- Look for bent lugs or a stray wire touching that switch, and for bent relay switch tabs.
Fix
- Re-gap the hundreds unit's 9-position switch so it is open (a couple of millimetres) except at 9, then test in a game.
Turn the game off and unplug it before reaching into the cabinet; EM games have line voltage in the cabinet.
