Bally Triple Bell Odds Changer

[pinball777]

I just picked up a Bally Triple Bell, it was free except for the workout of taking it up a flight of stairs to get it outside and down a flight of stairs to get it to my truck. It needs a lot of minor work especially cleaning.  I started with the Odds Changer and it looks like one of wiper arms is missing and none of the wipers have contact pads on them, as you can see in the picture. Can anyone provide me a picture of what it’s suppose to like? I’m figuring I’ll have to make new wiper arms unless some knows where I can buy them.  I’ll post more pictures of the restoration once I really get into it.
      Thanks in advance for any help or advice

A well calculated repair and partial replacement could be possible. A donor step unit would be needed.
Plus extreme precision and well applied soldering techniques.
Might be a solution if all other options are unavailable.

Thanks for the fast response, my biggest hurdle is figuring out what pad/row the broken wiper arm is suppose to sit on, a picture of a complete unit would be a huge help. I'm sure I could manufacture a part if I can't find a replacement and I have a good picture to work from.

Post a photo of the machine and any identification on the machine.
ID plate, hand written identification etc.
Wolftalk, has a database of most machines that contains schematics and unit diagrams.

I have schematics for triple bell and a very simple manual that has no unit details. 

the schematic shows a "rotary odds disc" and an "odds arm contact plate".  If you don't have the paperwork, I'll try and get it cleaned up and uploaded to https://bingo.cdyn.com/slots/ next week.

the rotary odds disc has a a few fingers that are all connected together controlling lights, and a couple more sets of fingers in the 120V circuit controlling the pay out units.

the odds arm contact plate circuits are mostly between the reel wipers and payout counter controlling the payout relays.

does the machine have labels on the parts?  If not, can you take a lot of high resolution images with good lighting that shows the wire colors attached to the contact plate(s) and either stick on a cloud drive/filesharing site or email to slotpics@cdyn.com.

the wipers may be factory.  The pacific pinball museum has a few flasher slots that nobody seems to want to buy off them ... not sure if there's any bally's but I'll take a look on monday.  I don't know if parts from a flasher slot would be useful for triple bell tho.

the worst case is you'll need to document the wiring on the back of the contact plate (which rivets are attached to the wire lugs) and the wire lug wiring.  From that it's usually pretty straightforward to figure out the wipers from the schematic.

Thanks for the replies and the information, I was lucky and there was a schematic inside the machine and its fairly legible. it doesn't show any mechanical drawings but at least I can tell what color the wires should be which will help when I start tracing the circuits. I included a few more pictures and as you can see this machine had a rough life but for me the fun is bringing it back from the dead. The front door coin mechanisms show how badly it was maintained. The only hand written number I saw inside was 101 and there was 1 small tag on the backdoor. I also included a couple pictures of the Odds changer before I pulled it from the machine. sorry about the picture's, I must be doing something wrong, it seems any picture that was taken in portrait rotates and displays in landscape.
