I need to ask for help on my restoration of my Gottlieb Big Indian before I go mental. Game is so close to being perfect from cabinet to play field, yet I can't get the game to play correctly. On all 4 players, when scoring 10 points, when you hit 9, and than 0, it does not add to the 100 points so for example, if you score 50,190, the next 10 points will only have the score reels at 50,100, not 50,200. All other numbers add correctly.

Second issue is the bonus count down. The stepper unit fires when ball drains, lights count down as they should, but no score is added to the score reels.

Rest of the game appears to work as required. Game boots up and resets, plays 1-4 players, drop targets count and reset, bonus units light up, rollover targets work, Vari-target works as it should, etc, etc.

I can't help but think somehow the two issues are related. Contacts were cleaned, etc and seem to be all contacting as required. I have the wiring diagram as well as the manual from PBresource. PLEASE help and point me into a direction I may be missing. Could it be the player unit in the backbox? Something on relay L, M, A, F, N, or the score motor that may have I missed?

Any help would be greatly appreciated

Thank you,

Jason

Inspect and diagnose this circuit with Alligator clip jumper wires, Starting with this switch on the 10 Point relay (N)

If the 1000 Point relay (L) doesn't activate when this happens, Inspect and diagnose this circuit with Alligator clip jumper wires

Oh this is maddening. First I only had the two issues. Than I moved the game from the garage to inside the house so it won’t get any issues with moisture. Now the 10,000 point won’t score as well.

I did at least verify that with L cool jumpered from Britain-wh-red at the coil to the red black at the bounce switch, it registers 5,0000 points for some reason. Not just the bonus that is lit on the playfield.

At N, the ten point fires, but does not add to the hundred relay once you get past 90. Same now as the 1,000 points. It just goes to 09,000 and if you add 1,000 it just reads 00,000. Wasn’t doing this before. Ahhhhhhh

If I am reading the wiring diagram correctly, the player unit has an effect on the bonus as well as the ten and the ten thousands units? Plan to Completely disassemble it and clean all contacts , and verify continuity on each wire for that disc that maybe were not cleaned properly.

F relay, 00-90, only moves during 100 points. Should it be moving for all score reels? Seems like it should move for the tens unit, unless this is just for match feature on the print.

Don't touch the player unit! The PU has nothing to do with your initial problems that HowardR addressed in his posts.

Did you have a chance to look at the schematic?

Yes, that’s why I thought maybe the 00-90 F relay or an issue or the players unit in the backbox. I jumpered the L relay, and the 1000 relay fires. But 5 times. Didn’t matter if I had 1k or 6k on the bonus lights. But with no jumper, no points, no chimes when ball drains. But stepper unit counts down and the lights count down. Score motor issue??????

By jumperimg M relay, the 10 points go, but still doesn’t advance to the hundred position. Just 90 to 00.

And now, for some reason, the 10,000 point does not register. You get 09,000 on the score reel and never advance into 10,000 for some reason. Odd since it worked before I just moved it to inside the house. Did take the head off, but connected correctly. Wondering if a broken wire is the culprit??????????

Well as you stated, players unit did nothing to help, but it did need a good cleaning, game had no backbox door. Still have same issues. Cleaning/adjusting contacts related to the print after I use jumpers to narrow the issue. Slow progress with new chores directed by my wife. We will see how it goes.
