I’m working on my newly acquired F-14. Originally only had GI upon start up & display was out. Checked and replace power supply, display and 2 transistors on MPU. Game then booted up and all seemed fairly well. I proceeded to replace much needed rubbers and flipper bats. Now when I start up I get all the coils firing one at a time like it’s searching for a missing ball on the play field. I’ve got 4 balls installed in the trough. When I check the trough switches I get a chime for each switch when tripped. Could any of the EOS switches be causing this?

Thanks wayout I’m going to check those switches out with a ball ASAP.

Ok, so I tested all the switches in the ball trough. They all work but don’t register the correct switch in the switch edge test.
Outhole displays as right sling
Left ball trough displays right drain
Left center trough displays left drain
Right center trough displays right flip lane
Ball shooter lane displays top left loop

Also found 3 switches that aren’t working
Middle ramp switch #31
Right center eject #23
Line of death yakov #55

I didn’t have this problem until after I changed flipper paddles and installed new rubber kit. I’ll check wire color to trough switches but 3 switches still not working on upper playfield. Need to determine if it’s a playfield switch shorted or MPU issue.
