After the head was refitted following shipping, the tilt light stays on. A game can be coined up and partly played, but the flippers don't work.
Tilt light stays on and flippers dead after reassembly: ball roll tilt switch closed
Cause: The ball roll tilt switch (under the playfield) had ended up closed. On this game it should be normally open, unlike the plumb bob and slam tilts, which are normally closed here.
Checks
- Check every tilt switch against the manual: the plumb bob tilt, slam tilt, playfield tilt and ball roll tilt, and whether each should be normally open or normally closed on this game.
- Check the tilt connector pins on the CPU board for corrosion and confirm continuity from the pins to the tilt switches.
Fix
- Set the ball roll tilt switch so it is open at rest.
