New to Williams and this Black Knight. Machine passes all diagnostics that are built in, credits set to zero for free play. However with 3 balls in the shoot it will not start, even with 4. It is in attract mode, however pushing the credit/start button does nothing. I've tested the credit start switch it registers when in Diagnostic 4-18 I can change the credit value which is now at 0.

Power on, goes into attract mode. Just won't begin a game. I'm stumped.

Check your ballntrough switches. If the machine doesn’t see three balls in the trough, it won’t start.

Are the Ball trough switch N.O. or N.C.? seems I read somewhere they should be one or other something was different about them.

I have No clue what your talking about. Go into switch test and see if the switches are registering with each ball in the trough.

Normally Open or Normally Closed.

I've not tested with balls in machine, will do.

Just checking- you changed adjustment number 18 to zero?
The maximum credits adjustment.

Resolved, feel dumb now. When PF was raised #20 Kickout switch would be closed with a ball sitting in it, but when lowered it was showing open. DPO had tried adjusting and the leaf was twisted. Removed and repaired, cleaned with a sheet of paper. All working now!

ryan1234 yup 4-18 set to zero, all good!

Still some work to dow with flippers but I have a rebuilt back box boards so it's coming along slowly.
