Anyone have the startup cycle for Wms Stardust? Google and PInside searches didn’t find it. May never have been written up. A similar game start sequence might help though.
Thanks

Quoted from baldtwit:the manual and schem are on ipdb.org.
when you turn on the game, the lock relay isn't powered so the game over relay will trip if it's not already.
after that, the initial goal is to get the coin relay to power. That can be messy with all the coin denomination/coins per play jumpers, but manually adding credits and pushing the replay button should also do it.
when the coin relay powers, the score motor turns on. A bunch of stuff around schem F7 gets pulsed, resetting a bunch of units and powering the reset relay, 1-2 and 3-4 reset relays to zero the score reels.
when all the score reels are zero, the reset relay loses power and that allows the outhole relay to power when a ball is in the outhole and the ball release coil is powered.
there's some other stuff related to the bonus unit and spitting out balls in the eject holes. The key thing to figure that out is the bonus unit has an escapement coil that completely resets the unit vs stepping it down one step at a time.
is that kinda what you were looking for?
the typical problem is the score reels all zero but the hold-in circuit to the reset relay doesn't open. The game sits there with the score motor running and never finishes reset, so no ball is served to the shooter.
Thanks, had downloaded the manual and schematic. The game is not consistent in how far it will get through the reset sequence and the manual didn't have the step by step some manuals do. For example one time it will reset the score reels, the next time it won't, or it will reset two of the players and not the the other two. And has done this both before and after cleaning and adjusting all the score reel switches.
And someone did the lovely drill a hole in the coin door and put in a button to bypass having to drop coins, instead of just tweaking the credit relay switches to "free play". In doing so, cut wires and left them dangling. So just trying to work through the issues to get it to start a game. Will be a few days before I can get back to it, but your step by step should help.
Thanks again.

Ok, finally got back to it. Score reels reset, bonus unit resets, replay relay releases, coin relay doesn't (not sure if it is supposed to release or at what point in start up) and when I manually open it, it closes again, score motor runs, playfield kick outs fire repeatedly, credit unit add credit coil fires rapidly till maxed out at 19 games then fires in sequence to the playfield kick outs, the coin unit fires in the same sequence, and the game counter adds games in the same sequence. So no problem. LOL Cleaned and checked basic operation of the coin unit and credit unit steppers, cleaned and gapped switches. Have checked every switch in the score motor, cleaned all and adjusted a couple that weren't making good contact. Checked all playfield switches. Any suggestions would be appreciated, but will just keep trying to follow schematic circuit paths and tracking down issues one at a time.
Quoted from baldtwit:if you're getting replays added, then most likely a switch on the 10 cent or 25 cent relay is stuck closed, or one of those relays is being held powered (coin switch stuck down, plug not in the right place, etc.
suggest you deal with that first as the game is probably continuously cycling.
Thanks, will check that when have a minute. There were many minor and some major hacks on this machine. So working through those also. One of which is a drilled through the coin door free game start button with wiring tapped in to the coin slot switch wiring. Guess someone didn't know the close the switch on the credit unit trick. I have been hoping that hack wasn't my problem as it looks done long ago. But...... may be time to tackle that one next.
