thanks for post-8. Before really digging into the schematics I would like to ask some questions:
- Did You buy the pin with the fault ? Or did You have a fully running Alpine Club and the fault showed up ? Showed up all of a sudden, permanent ? Or showing up sometimes - then more and more often - then permanent ?
- Did You do some work on the pin and then the fault showed up ? Did You adjust the gapping on switches ? (switches on relays - Tilt-Switches ?)
- Did You adjust the leg-levellers to make the playfield less steep ? See here http://www.stevechannel.com/tiltmechanism.htm , last picture, the ball rests on the left --- the ball is not allowed to roll to the right (and so closing the Ball-Roll-Tilt-Switch***). (((Also - on the 2nd last and 3rd last pictures we see weighted Tilt-Switches)))
Toggle-off the pin and unplug the main power cord (Safety Reasons) --- can You (temporarily) put a rubber band to help pulling - to the spring on the Relay-Bank so when You manually actuate the Reset-Arm on the Bank: Mechanically the stuff works (beeing pulled back all the way) ?
A little bit of temporary cheating: See in Your pin on the Coil on Tilt-Relay - from one side (solderlug) on the coil runs a short wire to a switch*** mounted on the Tilt-Relay - see it ? A little bit of cheating: Sneak-in a stripe of paper into this switch*** making the two blades always separated. Plug-in, toggle-on, start a game --- Can You play now ? (((The sneaked-in stripe of paper hinders the Tilt-Relay "to actuate". Of course the stripe of paper shall only be in the switch*** for a while --- but with it: You can play.)))
Toggle-off the pin, unplug the main power cord - take the stripe of paper out - so the fault can happen again - manually reset the Relay-Bank, plug-in - now watch the Tilt-Relay as You toggle-on (maybe by pressing the left flipper button) - does the Tilt-Relay actuate ? (From Your schematics I say: It must***) Start a new game --- at what time the Tilt-Relay faulty actuates ? Does it faulty actuate when the Reset-Relay changes from "pulling is resetting stuff in the pin" to non-pulling ?
See the JPG - "Ball-Roll-Tilt-Switch*** is my blue number 7", "this switch*** is my blue number 1", "it must*** is caused by my blue 5", "my blue 2": At the end of start-up, resetting: The Reset-Relay let go means my blue 2 moves into state "as drawn in the schematics" - now through "blue 2, 3, 4" and then along "my light-blue lines": The fault may show up.
