Will you do it?
CAUSE
~ An
intermittently grounded
• switch strobe line. (Typically the
green wire with the yellow trace
on the left Drop Target bank is
pinched against the playfield
support bracket.)
SOLUTION
Check the wiring on the left Drop
Target bank to make sure that
none of the wires can be pen-
etrated by the playfield support
bracket on the left side of the
cabinet.
PROCEDURE
If the wires look like they might
get caught when the playfield is
in its normal position, dress the
wires away from the edge of the
playfield and secure them to the
harness with electrical tape or a
tie wrap. This should prevent
them from drifting back where
~they might get caught between
the playfield and its supporting
bracket.

EQUIPMENT
All bill acceptors and games em-
ploying opto switches.
PROBLEM
It is often difficult to quickly de-
termine if the problem with an
opto switch is in the LED or the
transistor portion of the unit.

Purchase a Infrared Detector
Probe. I found an inexpensive
probe available from MCM Elec-
tronics that measures 4. 75 "x. 75"
for $6.95, part #72-003. This
probe is simply a piece of plastic
that glows pale orange when in-
frared is present. The size of this
probe works well in bill acceptors
and pin game opto units where
accessibility can be a problem.
PROBE USE
You can quickly determine which
half of the opto assembly is the
problem by simply exposing the
probe to the LED.
NOTE

It is easier to see the probe glow
under subdued light conditions.
Also, test both halves of the opto
assembly if you are not sure
which half is the LED portion.
