After finishing a Williams Dealer's Choice I'm now working on a Four Million B.C..
I got the game in playing condition, but this took longer than the Williams machine. I can't find any info about the relais used in the game.

The manual I have from the DC:

Is there any documentation about Bally in the way Williams provided?
Since I have a Camelot in queue with a lot more problem I would like this info.

Manual and schematics are on IPDB:

If you look at my original post you see I already discovered IPDB. It's huge source of info.

The manual I have from the DC:

But I like to know if there is a more detailed manual of Bally pinballs.

This is an image from the Williams manual:

What is yours doing that you do not like?

My FMBC is doing ok now i think, the only thing is, it took a long time to dig through the schematics and locate the corresponding contacts inside the pinball. With my Williams pinball this is easy, just look up the faulty relay in the repair manual and you can see all the contacts and where they are in the schematics and what they should do.
My concern is there wil occur some more problems in time. And probably I want know the schematics as well as I do now by that time. This means I have tor dig into it again.
If I don't find any info online I will write out my own overview. If there is some animo I'll post this to this forum.

Oh I see.

No, the Bally documents for 4MBC do not seem to have the type of (function of switches) info that Williams did. Maybe this Bally guide will help you even though it is not for any specific game? There is some good troubleshooting techniques at the end:
