ROWE BC-315 CHANCIER NOTES
BALLY PINBALL FLIPPER ASSEMBLY

ROWE
I
■ C-315
t has been well over a year since I pur-
chased my first Rowe BC-35 Bill Changer.
This machine is a major refinement of the BC-
25 (which is definitely a good machine). My
early BC-35 units had problems with a double
stacker. Bills were being torn and $5 bills
were mixed up with the $1 bills. The new
update kits completely eliminated all of these
stacker problems. The hoppers have a lip so
money can't be dumped out. The transport
has a major improvement- a belt that returns
odd pieces of paper. The belt is usually 95%
effective. The PCB is located at the base of
the machine with large heat sinks where
needed. I have had no board problems with
any of my units. The hoppers can now be
secured by an inside lock. The lid also has a
more secure hinge.
There are a few minor problems remaining.
The test-vend cover is not self-closing and
may be tripped with a wire. A new stainless T-
handle by Medeco has recently become avail-
able. I haven't been able to get one as of this
writing, but it looks good. I must also warn you
about National Lock. If you have one in a
changer, replace it with something else. You
can be locked out of your changer! I mailed
several locks back to them that I had been
locked out of, and their reply was that they
can't be duplicated. One thing I don't need is a
company handing me a line because they
can't do their job. Repeat ... repeat .. . replace
all National bill changer locksll!
The small hopper by Rowe is what I con-
sider to be poorly conceived. It will hold $500
only if you shove the money up and al I the way
back. The standard bag of quarters is $500. If
a quarter is spilled to the rear, it may fall and
jam up the auger. A thin bead of silicon should
help you in this area. The larQe hooper is

excellent, but a complete rip-off. Strong words,
but when the big hopper costs $2 more from
Parts and ten times that amount extra from
Sales, someone is kidding someone! To charge
almost $100 extra for a proper sized hopper
just isn't right. Also note, ·there are different
hoppers for different sized coins. The original
machines also had a lamp lens ttiat could be
removed from the outside. Thankfully, this
has been corrected. The coin entry has been
as much trouble as the rest of the machine.
Twice lately I have had debris jammed in the
coin entry causing the coin return button to
stay down. (Of course, this puts the machine
out of order.)
BALLY PINBALL FLIPi;IIER
ASSEMBLY
B
ally has had problems with their coil
stops and screws breaking on their
flipper assemblies for several years. This
condition on a game may cause it to lose
money for one or two weeks, depending on
the cost of the service call. Number 1 0 screws
should be put in place of the number 8. The
original base plate may be drilled and tapped
with the proper size or replaced with a new
one. The Bally part numbers needed are as
follows:
Coil stop - A365-24
Coil stop screws (1 0x32x6) - 17-1 0 1-467
Base plate - 365-101-XF
Also coming soon are smooth coil plungers. If
ypu have rough ones, I recommend using a
drill to turn the plunger and then sand it with
#320 and work up to #500 or #600. Tungsten
contacts are also coming shortly. This will
leave Gottlieb (Mylstar) as the only company
that doesn't use them for their end-of-stroke.

TRACK & FIELD MISSINCi VIDEO CURE
BY SAM CROSS, ELECTRONIC TECHNICIAN,
GODWIN DISTRIBUTING, N. LITTLE ROCK,AR
PROBLEM: Lower half of picture missing.
CAUSE: Because of excessive vibration of
the panel from people pounding on it, usually
on games not equipped with the special buttons,
a certain capacitor in the vertical section of
the Wells Gardner monitor, C313, a large
electrolytic capacitor, will tend to break loose
by either breaking a leg off or breaking loose
from the copper traces on the bottom of the
monitor PCB.
CURE: Repair the capacitor's failure condition
and install pound-proof buttons on the game,
or cushion the capacitor against vibration.

n order to prevent the accumulation of
free credits by kicking the coin door, a
slam switch should be added.
In all cases, the switch ( a "normally open"
weighted reed switch) should be mounted on
the coin door. Connect one side of the slam
switch to the brown wire on the coin switch
(ground). The other side of the slam switch
should be connected to a wire which will be
run through the wiring harness to the CPU
board. At this point the installations vary for
the four (4) games.

CORRECTION
In our April issue (Vol. 6, #2) there is a typo
