Tech Help: Gottlieb Sing Along....an ongoing thread

Ok, Y activates the C relay, which just sits there and holds, nothing happens.

'N' is located in the backbox (N, M, and L are the one, tens, and 100s points relays).

Does the score motor run when Y and C are active?

Check your diagram, C should be a motor contact... If there is then its dirty...

And here's what I mean by a motor contact. On this game (not sing along) there are 10 relays that will run the motor (Roller Coaster)

I cleaned both C and Y really good and they seem to be adjusted properly. Score motor does not run when either one is active.

yeah, the path on Sing Along has a bit more in it.

So it's a normally open switch on C that causes the score motor to run, but it also has a few other normally closed switches in series with it in order to do so:

- switch on Y
- switch on P
- and the Rollunder switch

Guessing maybe the rollunder switch is open.

Bingo, that was it! YOU are the man DF!!! Thanks!

Haha, ok, now this thing is just messing with me. I had the playfield up and I adjusted the rollunder switch and everything seemed to work fine! I went ahead and finished the game out by hitting the trough switches in sequence. Turned the game off and lowered the playfield. Now, when I coined up and turned the game back on, the score motor just runs constantly. The only way I can get it to stop is if I lift the playfield slightly and 'tweak' it just a bit counter clockwise, and I mean slightly. That said, when the score motor isn't running, it will not start a game now. WTF!

I checked the rollunder and that has no effect on it now.

That might be related to lack of the brake switch blade (letting the motor overshoot home a bit).

Does it make sense that the motor worked fine before? Also if I twist the playdield some it stops?

Sounds like it's hitting a switch somehow (missed the part about twisting the playfield earlier).

Candidate relays are C, U, W, O, A, G, DS, motor 1C, and SB (yeah, long list, but it's one of those switches making it run).

As a relay bank unseated? Jones cable getting pushed into something?

Now twisting the playfield doesn't do anything. I unplugged the playfield and the problem remains. I have looked over everything visually and I don't see what it is. I may have to take the relay board out and go over it.
