The Tools
Let's look at specific tools. A tool box without tools
is just an empty tool box. (?) This list covers, in no
particular order, the sorts of tools I carry and find
useful. It is just a guideline.

Depending on your job, your route, your experi-
ence, and the types of equipment you work on,
you may not need all the tools I keep, likewise
you may carry some that I don't. I don't carry vise-
grips, but some techs would feel lost without them.
Different strokes ...
Most of us build up a tool kit over time, we don't
buy all the tools at once. Some operators issue a
tool kit, and some technicians want a second kit
for travel or some other purpose. In those cases, a
complete kit is put together from scratch. The cata-
log suppliers offer a variety ofloaded tool kits. That
is one option to consider if you need to make a
complete kit.

Don't waste your money on cheap tools. You
will never be disappointed with the best. Cheap
tools bend, break, or strip far too easily. They can
even damage your work, stripping screw heads and
so on.

Screwdrivers - aside from the standards like =#=0,1,2
Phillips and a collection of slot head drivers, you
should consider some Pozidriv drivers (in several
sizes similar to Phillips). A big =#=3 Phillips is useful
on large screws like on air hockey tables. I find an
extra long =#=2 Phillips is extra handy often.
A magnetip driver not only holds the screw for
easy starting, but it allows you to carry bits such as
tamper Torx, Allen, square recessed, or clutch head
instead of whole drivers, handles and all.
/ Last but certainly not least, the Xcelite "99" series
f handles and snap-in blades cover most screw-
driver types including tamper Torx. Lots of driv-

WILLIAMS WPC POWER DRIVER
CPU RESETS SYMPTOM
PROBLEM
When the pinball is in play, the
game will randomly reset. Or,
resets while sitting in the attract
mode with no play.
NOTE2
Another reason these bridge rec-
tifiers fail is that the screws that
hold the heat sinks on, come
loose and then the bridges over-
heat. Be sure to visually check
these areas.

Check to see if there is low AC
voltage present at the outlet. If
the AC voltage is correct (ap-
proximately 115Vac - 120Vac in
North America), then change out
both bridge rectifiers BRl and
BR2. These are the ones with
heat sinks mounted on them.
If the AC voltage is lower than
recommended, then find an out-
let with the proper voltage and
retest the operation of the pinball.
If the resetting continues, then
change the bridges as above.
NOTEl
BRl supplies the 18 DC volts
BR2 supplies Ql, the +5 volt DC
regulator which supplies power
to the digital circuitry. See figure
for bridge rectifier locations .
