Good Day All,

I don't think this is right, but I need to verify.

Williams stardust, bonus (single, double, and triple), extra ball (when light is on) is always awarded as soon as arrow turns and points to it. I believe it should only be awarded when it drops it tge saucer or kick out.

Any help would be appreciated.

Thanks

You are correct. It looks like a NO eject sw. (E) at 15C on the schematic might not be gapped right.

Thank you for the reply.

This may be a clue, but the E relay coil does fire when the advance unit advances. Sometimes the firing of the E relay is only very small. Example not a complete activation. I will have a close look at the switch that you have mentioned.

I meant the "E" sw. on that relay. Check out the manual: http://mirror2.ipdb.org/files/2359/stardustmanual.pdf

Having a "small" firing/connection would make sense if the contacts are just barely touching.

Turns out that one of the eject switches was gapped too close, the vibration was enough to make it close completely and pulse the eject relay therefore awarding bonus without going into the kick out hole.

Thanks for your help.
