Ball waiting error. Game worked great for 10 years. Weak lower right flipper, so I decided to completely rebuild both of them. Replaced right coil and the contact switches. Then replaced the micro switches for the 3 balls. Still ball waiting when I press the credit button to start the game. The game works fine in switch test mode. Not sure how to proceed. What could I be missing?

Sounds like a loose switch in the ball trough. All 3 must be working and making contact for the game to start. Check for broken diodes on the switches as these will cause them not to register as well.

I replaced the diodes as well. Can you get them backwards? I did not replace the 1st switch yet as this micro switch is different then the other 2.

You shouldn't have to replace a coil to fix a weak flipper unless it was sketch to begin with. It's usually related to mechanical binding, poor switch contacts and bad solder joints.
