6. Some older cabinets with CGA monitors have an AC isolation transformer that is used to
power the monitor. These are often bulky, heavy transformers that take up most of the
space on the bottom of the cabinet, and they cannot be removed unless you replace the
monitor. If you connect a monitor that requires an AC isolation transformer directly into
an AC power source, you will damage the PCB chassis on the monitor.
7. If your cabinet has an AC isolation transformer for the monitor, find the AC power lines
that power the AC isolation transformer and splice them to an AC power cord (not
provided in the kit), so you can connect this to the AC power strip. You may need to
reposition the AC isolation transformer to make room to install the computer on the floor
of the cabinet. (Note: The new Wells-Gardner
®
monitors do not use an AC isolation
transformer. If you are installing this monitor, you can safely remove the transformer.)
Remove the Game PCB and Install New Hardware
Caution: Power must be off when connecting boards. To prevent damage from
electrostatic discharge (ESD), handle PCBs by the edges only and use a grounding wrist
strap or similar precaution.
1. The Conversion Kit hardware uses the existing Jamma harness wiring for speakers, video
(for an existing monitor), and coin inputs. Remove the Game PCB and any other
hardware from the old game, but keep the existing DC power supply and Jamma harness
wiring in place.
2. Install four small plastic feet from the kit on the Jamma conversion board, and on the
UVC if you are installing one.
