Hi all,
I'm working on my 1st restoration project witch is a 1964 EM 2 player Bally 50/50.
I have come across a part that so rusty it's falling apart I think its a resistor but I'm not able to read anything from it.
The resistor is located on the 1st player tilt or hold relay.
I have tried to get a reading on with a multimeter with no success. Unfortunately, I don't have the schematics and I have not been able to find them anywhere.
So my question is does anyone know what resistor is used or where I can find the schematics?
Also, I hope everyone's had a great Christmas.

Did you try PBR? http://www.pbresource.com/

You could look for clues from similar schematics on IPDB.org like this one from Campus Queen made the following year:

This game uses a 15 ohm resistor in series with the KK-332, 100 ohm Hold relay. If you can find another game or two with a similar arrangement that might confirm what you need.
