I have worked out the big gremlins that were in my game. Now that I'm able to play it I've noticed that it doesn't award extra balls consistently. Some games it awards them correctly and other games it doesn't award them at all.

What would I need to look at to get this fixed?

I believe it randomly works/doesn't work on those switches, but will need to double check. The main time I've noticed is for achieving a set score. I believe it is set to award an extra ball for 240,000 320,000 and 410,000.

The match feature was on. I cleaned the male part of the jones plug and moved over to off. For the first couple test games it worked right but then did what it was doing before. I checked and cleaned the make/break on the game relay it looks good; I could have maybe tightened up the gap a bit on the switch that is normally closed but it was making pretty good contact so I left it alone. I think the switch on the score motor you are referring to is on switch stack farthest from the score motor gear box, bottom most switch. It looked ok. I went ahead and cleaned the switch, it was like the switch on the game relay where I could have tightened up the gap a little bit but it was making contact so I left it alone.

I lit and checked the three special switches and they award an extra ball 100% of the time so it appears the problem is in the scoring portion of the extra ball.

Anything else I should look at or do?

Not sure if this is related or not, but thought I should mention it. Every 1 or maybe 2 times I start a game it will start at ball 4 and not ball 5.

HowardR, I did as you said, I studied the 2 links you provided and gave it a shot; thanks for the education! I have a couple general questions I will ask at the end.

During the test I had to skip the W-Gray on the 10,000 point drum because I couldn't tell which one was W-Gray, can you tell from the picture? I went to the next step which was the 10,000 pt relay and I could not get the ball count unit to advance like it did everywhere else. Is the B-R wire bad somewhere?

I noticed on the schematics on the 100,000 pt drum I was supposed to check the BLU wire, there is another number next to BLU, maybe a 5, or letter after it that I can't read; same with the wire on the 10,000 pt drum, looks like a 4? What are these numbers/letters?

Quoted from HowardR:

Which wires to check on the 10k drum, the 100k drum, and the High Score Adjustment depend on what you have the High Score Adjustment set to.

The card on the apron and the way it awards balls when it works is: 240,000 then 320,000 then 410,000

Quoted from HowardR:

If your schematic is more readable than my copy from IPDB you should be able to tell from the wire colors next to it. If your schematic is my same blurry copy, I suggest you buy a good hard copy from one of the usual suppliers.

I printed my copy off of IPDB so it's about the same thing you have.

What should I look at since the B-R wire isn't activating the extra ball on the 10,000 pt relay?

Quoted from Pmedic871:

:-)From your prior thread on Blue Chip "I still get 5000 points, the minimum bonus, lit at the start of a ball," I also own blue chip and this is it's correct functioning. Reading this thread I will say that my instruction card indicates free ball at 2 scores and awards properly upon achieving the lower score but does not at the next score. I have not tried to fix this but is probably just a jumper setting.
BTW I have the original schematic and manual, should you need a reference.

I watched a couple videos and noticed all of the Blue Chips in them also start out at 5000, seems weird, but like you said it is correct. I took apart my score reels and cleaned everything hoping to fix the extra ball problem, but it still intermittently awards extras balls; I'm going to work on and post about it more when I get a chance.
