Williams has made several improvenents to
ensure the quality performance, game
playability, and reliability.
IMPROVEMENI'S INCLUDE:
1. 'Ihe bK> upper flipper coils have been
changed to FL11722 (green label). These
coils provide a longer life span for the
upper targets, along with better
playability.
2. A change in the lighting to alleviate
p:>ssible transistor failure (Q42).
a. Renove the three Phillips screws
left, center and right, shown in
Figure 1) that mount the top loop
plastic assenbly. Remove the top
loop plastic assenbly from the
playfield.
b. Unsolder the wires from the bulb
socket (a.FAR, Figure 1) near the
"C" in CAT. Push the four wires
through the playfield. Resolder the
two orange wires for a proper
electrical connection. Tape ends of
soldered orange wires with
electrical tape. Separately tape
the ends of the white/violet wires.
wire to the bottom tab. Using a
1/4" socket wrench, renove the wood
screw that xoounts this "A" bulb
bracket to the playfield. Renpve
the bulb, socket and bracket.
d. Unsolder the wires from the bulb
socket (RED 1, Figure 1) near the
"O" in TOM. Push the three wires
through the playfield. Resolder the
two orange wires, and tape this
soldered connection. Separately
tape each white/violet wire with
electrical tape. Using a 1/4"
socket wrench, renove wood screw
