Roz, it was nice to meet you, too, and thanks for the kind words.
I will say one thing however to the readers here --
The only advantage I have on most of you is that I have been working on these wonderful e/m's longer than you in most cases.
Don't mean I'm smarter, just I have had more time on them.
Most everything you will need to know you can find in the free downloadable bally manual.
It has parts views, parts names and descriptions, switch functions, and most importantly, there are some rudimentary schematics in there.
The little secret here is that MOST of the functions of most of the different models are identical, and even oftimes the wire colors are the same.
Also, I taught how to fix these things when working at gaming schools here in Reno decades ago, and was asked a lot of questions by students that I had to find the answers to in order to pretend to be legitimate.
The bally manual is about the best source of info that I know of.
The second best source is the masters who frequent this board, like OpBell, and some others.
Thanks.
