Hello again, I just picked up 1977 Gottlieb Jacks Open. I tweaked some minor worms but I'm stuck on Point adjustment score, it simply doesn't fire at all at any point structure. I have the replay score set at 130k 180k & 190k. It awards replays when you score the lit "special" target but won't award anything on points! I will send schematics(for education purpose only) I have a cheap phone, so I couldn't draw what I think is the path,

but basically I'm following the path yel-bl wire to the make it or break it switch "jx" with a mar-or wire or Mar+yel to point score adj then out through 10k unit down to "15 pos switch" which should be closed to fire "add replay unit". Am I missing something? If not where is this "15 pos switch" located ??? That's the only thing I can't verify. Thank you. I will be back at it Tuesday afternoon. Hopefully one of you guys can leed me to the right track... Another problem is some relays are missing that nice yellow sticker to identify relay#. But I got most of it sorted out talk soon :0)

Ok *damoib* I will look into this matter on Tuesday. I appreciate any help

Ok @Damoid. Look like that yel+ gr wire is attached to c-position
Now for the match replay feature, it dosent knock and it dosent reward the free replay

It only awards a replay when you go through drop target sequence and the red light goes on for "all targets down special" if you get all targets down you get a replay and knocker

I will be back at it this evening when I get home. This worm has really got me puzzled.

@Damoib. Late night early morning again...m

Ok jumping those two wires on 10k score reel works. Knock and replay every 10k points

I re-checked score motor4d. Switch looks gapped correctly, gave it a courtesy clean, yel-bl wire is intact .

Ok Mar-Or wire from "JX" relay was jumped to the Yel+Gr wire from 10k reel, as a result it does not knock or give replay at any 10k scoring. I set the score at 130k 180k 190k. "1" jumper is set at 30k. "8" jumper at 80k. And "9" jumper at 90k

Also by jumping those two wire, didn't activate JX relay. During normal play the JX relay does activate properly, and light 100k light

Yes you are right @DaMoib. There's two yel+gr wires... One welded to jumper the other welder to the C tab on reel

Ok thank you guys for helping me. I will be back at it on Friday. I will call Steve pbr tomorrow morning, I was going to order parts for abracadabra, so I will add some jacks open to the list DaMoib the colour of the broken contact if I remember correctly was 3 colours if I recall. Black+red+yel. I will clarify it Friday. Yes I didnt see any broken switch blades. I acquired this machine last week so I vacuumed so of the dust. I wouldn't be surprised I vacuumed the switch blade :0( also the soldering of yel+gr wire in 10k reel jumper looks like amateur solder job, deffently not gottliebs

Still waiting for parts
