New to EM here. Acquired a Gottlieb Scuba which worked when I picked it up. When I got it home, I can select one or two players. However, after ball 1 drains on Player1, it immediately lights Game Over.

-Checked the tilt switches and they seem to be working correctly.
-Manually advanced coil on player unit and verfied the ball number advanced and lights up correctly through ball 5 and game over for both players.
-On startup, the player unit resets correctly (i.e. the coil is working)

Any ideas on what I should check next? Been reading up on everything EM as much as I can. These are a bit different from SS.

I was able to fix the problem. A switch wasn't making proper contact.
This machine is pretty filthy which is sad because I believe it has been in a home collection for a while.
