I realize this may be to a limited audience, but hope some others may have some insight.

I've finally got the bowler from gjd into the basement and setup.  On the first power up it seemed to cycle fine (scores, players, frames all reset properly), and adding coins works fine (number of players increases), however the game selection doesn't work and 'shots' don't seem to register.  By 'shot' I mean manually tripping one of the metal bars in the last row on the PF, as my puck is still in the mail.

Is there something I'm missing?

Mike, did you ever manage to scan the schematics?

Thanks

I've got a copy from a Royal Hawaiian.  I can't imagine it'd be much different.  But as someone said here it's huge, a blueprint scanner would be needed.  I took some pictures with my camera if you want, but they aren't really clear.

According to my service manual the machine always advances to "Regulation" on a reset.  Does yours?  Is the machine in tilt?  There is a 'Rear Roll Over Relay' on the back of mine that is energized by any of the 9 rear rollover switches.

Thank for the offer, but I'll wait for Mr.Mikeman to see if he scanned his first, save you the trouble hopefully.

Yes, it sets to Regulation when it starts.  There isn't any tilt indication.  The only thing I see is an anti-slam switch on the coin door, it's closed.  Is there another?

I tried again tonight and was able to get some pins to go up, I'm not sure if there was a loose connection prior as I did re-seat the connectors again prior to trying, or if I wasn't tripping both switches at the same time the other night.  At any rate, they go up, however nothing still seems to register (no scores, no frame reset when all pins are up).  I take it the score reels update at the end of the frame/player as opposed to per shot?

The rear roll over relay does trip when I hit one of the rear switches.  Although it also has a large resistor jumpered off of it, not sure if that's original or not.

Another odd thing, there are the individual lane lights on the underside of the PF, at what point do these light up?  I would think that they should be on as soon as the game starts.

Ok a few things..  

- No the schematics are not scanned yet.

- Scoring:  It's the same as bowling (when playing regulation).  So..  Score at the end of the frame unless a spare or a strike, then scoring is later.

- The lights under the playfeld are for the "Flash" game...  The flash in sequence along with the points lights behind tsmall backglass...  Quite fun actually.  It adds timing to the game.  i.e. you have to try to get a strike when the red lights are on for the most points.

- You'll probably have to 'loosen' all the stepper units.  They're mostly on the back of the door.  Get them to move manually.  I used non-conductive and non-dust collecting lube (VERY LITTLE) on the pivot points of the steppers and worked them by hand until they were loose.

- Yes the connections (big plugs) from the playfield may be corroded and cause switch problems due to bad contact.

- All the switches at the back are connected together and they count the 'shots'.

Hope this helps a little.  I'm away from home this week but I'm returning tonight.  I'll see if I can get the sheet scanned next week.

Thanks Mike, I saw your other post and knew you were out of town.  I'm still waiting on a puck so there isn't a rush yet.

In another thread you were talking about the different play modes, specifically the start button.  I'm starting to guess that there is a bad connection there.  The start button is gone, closing the switch does nothing, yet there is some power there.  Only half a volt though, not enough to drive the lamp.  Can you give me a overview of what/where any game setting connections/jumpers are?

I'm sure it's close, or something stupid/obvious.  It'd be a lot further along if it wasn't for those damn Olympics.

Thanks

The start button is disabled on mine too (and missing) and I still haven't figured out how to get that working.  Right now it's set up to start immediately when you add a credit and adds players after that.  Concentrate on getting to run correctly first then worry about the accumulation of credits and using the start button.

If worse comes to worse, bring it back and ill exchange it for another. What is the title of yours by the way?

Thanks for the offer, but I don't think it will come to that.  I'm sure it's something that can be figured out, not to mention that the only way that thing is coming out of the basement is in pieces.  It's officially a chattel now.

(I have one of the Civic Centers.)

Any idea why this wire would be cut? (see top lead of bottom coil, it's been cut and wrapped around the remaining wires).  It's on the motor by the pin mechanism (looking in from the back of the cabinet, it's on the top left).

Another angle.

what unit is it?

Is this the Credit unit ?

If it is, I have seen similar hacks in the past, where the credit substract coil is disconnected,
thus basically setting the machine permanently on free play (once credits are added, they
never return to zero).

I prefer the other method of changing the adjustment of the zero position switch on the EMs
Credit unit, to make the machine 'think' there are still credits even thought the counter is at 0.
In that method, the credits are still added or substracted on the unit as normal, but the machine
will still start a new game even if at zero credits...
