SUBJECT
Potential grounding fault on The Simpson's
games serial numbers 31788 to 32212.
PROBLEM
JAMMA Interface Wired
We have installed a new power box (all Metal) in
The Simpsons Pinball starting with Serial
#31788. The initial games have possible ground
fault problems due to the location of switch lugs.
In these games there is the potential for the
power lugs of the switch to make contact with the
metal grounding strip on the service outlet.
When this occurs the 120vac is applied to the
chassis ground of the machine.
Should this occur, the location's circuit breaker
or fuse should open when the game is plugged
into a grounded outlet. If, however, the outlet is
not grounded or the grounding prong on the plug
is defeated, a potential shock hazard may occur.

SOLUTION
To avoid this problem, starting with game Serial
#32212, we have rotated the On-Off switch 180
degrees to prevent the lugs from touching the
metal on the service outlet. In addition, we are
adding heat shrink tubing or electrical tape on
the lugs as an additional precaution.

you rotate the switch as shown and add electri-
cal tape to the switch lugs.
