Illustrated below are the most recent updates for
all our new games with coin credit PC board addition.
Some general guidelines to follow when setting up your new games with coin accumulation:
1. After assembly and installation into its
permanent location, toggle all dip switches
3. Check the coin credit board for the revi-
sions shown below. If they haven't all been
back and forth to be sure that they are
making good contact. There are 3 sets of dip
switches on the coin credit board (shown
below) and also one set on the main PC board
on 6000 and 7000 models. If any of these
switches are not making proper contact they
could cause missed coin-ups. It is a good
idea to repeat this exercise any time a game
is relocated.
made, please do them. These revisions
should eliminate coin-in problems, an
minimize any static lock-up problems you·
may be experiencing.

version... the Eprom on the main board
(U15) has a white label on it; it should say:

Nam.co Shoot Away Rifle Repair

PROBLEM
Shots have no light but the sound is ok.
CAUSE
As the rifles are dropped. the mounting
hardware inside them come loose and short
circuit the 250 volt DC lines. This blows the
power supply board. thus the Xenon lamps
(ze-non) won't flash.
SOLUTION
First of all, remove the plastic barrel cover
and repair all wiring and trigger PCB compo-
nents as needed. I recommend soldering the
wires to the boards and wrapping each
board in a plastic packing material, then
discard the U-shaped brackets and install
the barrel cover on.
PARTS REPLACEMENT
Next, with both rifles repaired, proceed to
remove the power PCB from the main chas-
sis for repair. On older PCBs, locate and
replace RI, R77 and REC I. On newer ver-
sions replace RI, R2, R3 and RECI. 100 to
200 ohms wire wound, ceramic, I Ow resis-
tors will be acceptable, and for the full-wave
bridge rectifier it must match these specs:
PIV = 400v (or greater)@ 2amps.
