Here I am asking for help on this machine again. Was playing fine, next time I turned it on it booted fine but there is a clicking going on some where and the light bulb under the Playfield on right side keeps flashing with click. Can’t press up a game. And also if I press left flipper a target and also a coil fires. I have new Alltek boards in it. And there booting with no problems. Any clues? Any one ever have this problem? Any help would be appreciated. Thanks

Get the schematics of the machine and verify each connectors.
What you hear under the playfield and see (light bulb) is the solenoid expander board. It is a good sign that you hear it (and see it).

Put the machine in test mode (little push button inside the coin door) and go through the various sequences.
Please, report what you experience.

Check your cabinet harness switch connectors (J3) and the playfield switch (J2). Sounds like the left flipper button switch matrix switch is being misinterpreted by the software indicating a switch matrix issue.

Went through test mode with no problems. I’ll check j3and j2. This weekend. I’ll let u guys know how I make out. Thanks for the help.

When you say "went through test mode with no problems...", are you certain that none of the switches were closed?
If you did not remove the ball from the playfield, at least the outhole switch should have been detected..... and maybe others too.

Ball was in game. It looked like everything fired. But when I turn game on now. it presses games up on its own and the coil inside the door goes crazy and one of the drop targets on left bank shakes. Lol. I’ll run test with ball out of game this weekend. Thanks arcane.
