PROBLEM
SUBJECT
Have you ever found any problems relating to
two balls being kicked out into the shooter lane
on Whirlwind (first one, then the next) related to
noise on opto circuits?
Williams Opto Drop Target update needed.
I have this problem intermittently, but fre-
quently enough that I get constant complaints.
My trough switches are adjusted perfectly and
do not get hung up. But when it happens it acts
as though trough switch 2 or 3 got hung up.
REMEDY

I haven't had that specific symptom Doug, but I
have had many intermittent trough switches
that can be detected only in "Switch Edges" test.
PROBLEM
Once again, the Williams optical drop target
Pcb's are a continuing source of problems in the
field.
The opto leads will break with or without silicone
cement applied, the connector become inter-
mittent. the traces are too fragile and the "E-
clips" which secure the board are too difficult to
remove and reinstall.
Operators deserve an upgrade for this monster
so that Williams' pinballs can perform up to
spec. I have seen too many Elviras, Whirlwinds
and Black Knight 2000s with one or more targets
not functioning.
SUGGESTION
Hold the switch down and tug on the lugs; an
intermittent switch will flicker on and off.
We need a rugged drop target board that will
stand up to vibration, be dirt resistant and can
be swapped in and out of a game easily.
NOTE
NO E-CLIPS, PLEASE!
PROCEDURE
I've also had a stuck switch in the left bottom ball
reserve lane that will cause your problem.
Sometimes these switches will not release every
time they are free.
If this cannot be accomplished, go back to the old
fashioned microswitch target banks that rarely
needed any attention.

PROBLEM
SOLUTION
Ball will Jump on top of the plastic below the
yellow metal ramp (next to the left lock) and get
stuck between two screws.
Remove the phillips head screw located next to
the side of the cabinet and the yellow metal ramp
entrance. The ball will no longer get hung up.
