Repairing Williams System 11 Pinball

Scope.
This document is a repair guide for Williams System 11 pinball
games made from 1986 (High Speed) to 1990 (Dr.Dude).
Some Bally games from 1988 to 1990 are also
included as Williams bought the Bally pinball name in 1988.
Updates of this document are available for no cost at
http://pinrepair.com/fix.htm
if you have Internet access. This document is three parts
(part one,
part two, and
part three).
The basis of this document came from the
WPC Repair guide. These two systems
are very similar in design.
IMPORTANT: Before you Start!
IF YOU HAVE NO EXPERIENCE IN CIRCUIT BOARD REPAIR,
YOU SHOULD NOT TRY AND FIX YOUR OWN PINBALL GAME!
Before you start any pinball circuit board repair,
review the document at http://pinrepair.com/begin,
which goes over the basics of circuit board repair. Since
these pinball repair documents have been available, repair facilities are reporting a
dramatic increase in the number of ruined ("hacked") circuit boards sent in for repair.
Most repair facilities
will NOT repair your circuit board after it has been unsuccessfully repaired ("hacked").
If you aren't up to repairing pinball circuit boards yourself or need pinball parts
or just want to buy a restored game, I recommend seeing the
suggested parts & repair sources web page.

Some people question whether I wrote all this material myself. I did, but of
course like everyone, my repair techniques and ideas are gathered
not only from my own experience, but from work that
others in this hobby do and share at shows, on the
internet, etc. So if you're the originator of some
cool trick or tip in this document, and I'm not giving due credit,
just let me know and I'll add you to the list of contributors above.
Why is this Document Available?
When I was first started fixing pinballs, I was amazed at the lack
of any books. So when I fixed things I wrote them down. This is a
cumulation of all those notes. The best book I found on WPC and System 11
was Norbert Snicer's Pinball Machines: How they Work & Troubleshooting,
1992. An excellent book which I highly recommend.
