GTB 2 Player Jumping Jack May 1973
To begin, I noticed I lost the chime on 100 point scores. Found 100 point M relay hung up as soon as any score is made, even 10 point targets.
Since the reels were a little reluctant to behave , I removed the now dreaded Decagon reel and went through it. I would like to know if I created a problem, because if I did not, at least I enjoyed that step, as it was straight-forward, except for no availability of the switch settings.I found some online on Youtube that seemed to make sense.
I can do all the others reels easily now which would be a sort of deranged "fun" compared to chasing my tail with these relays. Not sure if I caused any new problems during that affair, but the 100 pt reel coil plunger works smoothly, advances decently through each number when operated manually.
Problem now is, if i start a game, all is ok, but as but soon as any score is made, the 100's score reel, and the M relay both hang. I can unstick both by either manually levering the coil apart, or moving the stuck end of stroke switch on the score reel . See details below of hangs.
All of this is not happening on the player 2 score reel which uses the the same M relay.
I have placed paper under all the playfield switches I can find to eliminate them as a factor.
When I reset game, and manually close:
the 1o,ooo K relay, it does NOT hang, no chime, but it clicks the reel nicely, advances and scores.
The 1,ooo L relay manually operated, just chimes once, as it locks itself and the 1,ooo score reel requiring manual release of EOS switch
The 1oo M relay manually operated just hangs, with no score, and no chime, requiring manual release
The 1o N relay when manually operated does not itself hang, but it kinda chimes partially and hangs the 100 score real but NOT the 10 score reel
i have insulated all the switches to rule out playfield switches etc as a cause, and I think that is ruled out, hopefully,
I looked at the player unit, but could not do any work on it, as not sure of adjustment procedure. I also looked at score motor, also leery of making things worse. I do know where these are at least.
As usual, I made the mistake of trying to fix it by my self, and not asking for help. I like a challenging task, but this has had me bewildered for the last 4 days.
Now I am obsessed with fixing it. I stand ready with the measley PBR manual, and the schematic I had blown up at Fed-ex, with my trusty multimeter, trying not to make things worse.
Any help would be fantastic.
