Touching metal on the game, such as the tilt bob frame, makes a kicker fire and a switch number show in switch test, even with the game otherwise playing normally.
Touching the tilt or cabinet metal fires a kicker: broken earth wire in the power cord
Cause: The earth (ground) wire inside the mains power cord was broken, so the cabinet's metal parts were not properly grounded.
Checks
- Plug an outlet tester into the game's service outlet (if it has a three-prong one) to confirm the earth connection.
- With the game unplugged, check continuity from the cord plug's ground pin to the cabinet ground point.
Fix
- Replace the power cord with a new grounded cord.
