Bringing a Spirit of 76 back to life.
Lots of messed up switches and other hack items. Got machine starting, coining up and plays, now it seems that the drop targets which are to score 500 for each is only scoring 100 for each.
Before this post, the targets would drop but it would not add any score. After looking at the schematics, I checked relay D as that controls the 500 points and bonus. I cleaned the contacts, adjusted the blades, checked the wiring. All is good. I then checked the 1A motor and switches. The motor makes a rotation and I can count the 5 clicks of the A reel. I will see it spark the contacts once and then nothing. Again I cleaned and adjusted the blades on 1A and still only one score of 100.
I checked the wiring from relay D to the motor and it is fine as well.
Any ideas on what to look for now?
Thanks
Mike

Not sure what you mean by staying active? It pulls in at first and then it looks as if it goes back to rest position but the score motor will tick off the five times with only one spark out of the five. What would keep the relay pulled in?

Ok So I went back to the machine. I checked the switch and I cleaned it and I adjusted it. Adjust it too close and it fires all the time, adjust it too far and it doesnt score. Find that sweet spot and it scores 100 and that's it.

I ran a lead from brown/black to the score motor, no difference scores 100 that's it.
Checked the switch on 2B and it closes until it reaches the peg and opens. Put a test light on it to verify that.

Put a test lead from brown/black switch leg on relay and the other end on the org/white blade and still only scores 100 and then nothing.
I closed switch on motor 2b with jumper and scores 100.

Not sure what to look for now.

No the D/500 relay does not stay pulled in.

yes it does

thanks I will try that.

Since I had posted this on pinside, I was told to disengage the score motor and activate a 500 target. I did this and the D coil locked on. I turned the score assy and it hit the first peg and it scored 100 points. I turned it more and I heard nothing, turned it again and now a buzzing was coming from AX or BX coil. No score, turned again no score and the buzz stopped. I reattached the score motor and ran it again. It rang up 100 points clicked 4 more times and no score.

I decided to look at the AX coil as it was screwed up from the start of this restore. I checked gaps, alignment and looked for spinners. I did find the blades a little off kilter and adjusted them. I fixed the gap again. I then did the above again with only 100 scoring again. This time I heard the buzz from BX and adjusted it as the AX.
This time I started a game and it would not reset the score reels and would not reset the game. It did allow me to ring up points.

I figured I screwed up the AX or BX and took the AX coil and adjusted its gaps again.
I started the game but no resets of the score reels, but DAMN the 500 points now score correctly.

Seems that the terrible to adjust AX and BX were the roots of my evils. I adjusted AX and game reset and score 500 correctly but the game would not end. Get to ball 5 and keep on a going. I then looked on pinside and saw a ton of folks with that issue related to BX or AX out of adjustment.
I then watched Clay's video and adjusted the crap out of AX and tried the game, all worked except the 5 ball/game over. Then I adjusted BX and played it again. Goes to 5 ball and stops!!!

Now I have just a few minor things, pop bumper that sticks, couple lite sockets not working, 1 rollover not scoring on a consistent basis, and the worst is that sometimes the game stays on ball one for 2-3 balls and then works correctly. I am going to fix all the other issues and then play it alot, see if that doesn't work out the ball advance issue. If not I will adjust AX or BX again.
