Dynam.o Power Plus Supply Notes

Richland Hills, Texas
The correct pin-out is as follows:
• Red to White
• Green to Black
• Black to Green
SUBJECT
Just a word about your Dynamo Power Plus
150w power supply. Dynamo's supply is pro-
tected from over-current draw. If your supply
shuts down you need to check your wiring for a
possible short. It could be a wire has gotten
closed in the coin door causing a short. This
would cause the power supply to shut down.
ISOLATE
After checking wire harness for shorts, wait a
minimum of 30 seconds before restart. Turn
supply back on. It should restart. If not, unplug
power to Pcb at the power supply itself. Wait 30
seconds, turn back on. • If the fan runs you
probably still have a short in the wire harness
somewhere. If not, your power supply is bad.
RETURNS
This supply comes with a 1 year warranty. Do
not break the seal. Please return for advance
replacement. Breaking the seal for any reason
will void your warranty and you will be charged.
TESTING
When testing your power supply for voltage
levels it must have a load on the +5Vdc and the
+ 12Vdc lines. Checking the supply without a
load will result in erroneous readings.
AC NOTE
When looking at your AC output wires you will
notice that the wire colors do not match up. Do
not try to make the colors match. Doing so will
void your warranty and possibly cause
unrepairable damage to your monitor and your
game Pcb. The correct color match up is on a
sticker located by the DC pin-out chart on top of
the supply.

ers and countless other kits in Dynamo's HS-5,
8 and 9 universal cabinets.

PROBLEM
Your I player basketball game is locking up,
leaving the ball gate open, ending a 45 second
game in 5 seconds, and making wierd sounds.
SOLUTION
Check the 6-pin female power connector going to
the scoreboard. The pins might look ok, but they
aren't -replace and/ or rebend them to make
better contact with the male pins. Restart and
verify operation.

0PTO ORIENTED
When you attach it to the board, make sure you
have it in the right direction. The optic sensor
from Newark Electronics clearly indicates which
side is the detector and which is the emitter with
a transistor and diode symbol, respectively.
However, the original Williams component does
not.

VERIFY
The best way to make sure is to use a digital
meter to read the other good optic sensors on the
board. The detector side will read "open" both
ways while the emitter side will read like an LED
would (in fact it is!).
