Css-96

Hi..

Where is the best place to get a Manual? I see where I can D/L one online. But my question is, are all CSS-96 manuals the same?   Is there a difference between a CSS-96C,D, etc?

My trouble is.... I replaced the coin mech, but the gate still won't open. The Coin mech dispenses the correct change but the gate won't open.  

I was told to check the cellinoid, so I want to get a manual. So.. are all the manuals the same?  Thanks.
