Study up on getting into diagnostics. Tests - for switches, for coils ( pull out high power interlock on coin door to enable high power ) flashers, should be a test in there to for devices, if not the eyes and mouth would be in coils.

Have the seller show you how to do this.

easy way is to roll a ball over the sensor during edge test ... but if they are not properly adjusted they may not read correctly.

The bulldozer in front of ted's mouth and in front of Red's mouth. You can't test with your fingers, so you'll want to put the machine into switch edge test mode and then roll a ball towards the bulldozer targets and towards red's mouth. You should see those switches register on the screen once the ball gets within a close proximity to either area on the playfield. If you need more info, I'm happy to help. PM me and we can chat via phone. I can also explain some other items to look for.

The easiest way to test all of these things at once at least what’s listed is to hit the start button. Red should open her eyes, start talking with Ted following shortly after. That takes care of eyes and mouth. They should move side to side following switch hits from
The ball. Eddy sensors can be tested by hitting the start city scoop or the mine entrance. If you do it immediately New York should start and it will activate teds bulldozer. If you don’t want to start a mode just start hitting the bulldozer and it should callout the days of the week up until friday. I would bet on at least one of the heads having some component not working correctly but that alone would not discourage me from buying at all. The internal parts should all be available and able to be rebuilt if needed.

To go into more depth on the eyes...after looking left or right, they should snap back to center. Not lazily drift back, but snap back quickly. If they dont do this, the brass eyelets that hold the tension on the centering bar are worn and need replacement.

This is extremely common. Those eyelets are thin and wear easily.
