connect the
clear wire
to lug 3
(S-1
),
the
black wire
to lug 2
(S-1
),and
the
drain
wires
to lug 1
(S-1
)
of control
B. Make sure
the control
solder
lug remains soldered.
At
the other
end
of the cable,
connect
the black wire
to hole
K
{S-1 )
and
the clear wire
to hole
BC
(S-1
)
on
the circuit
board.
BC is not marked
on the
circuit
board.
Prepare a 16" black
hookup
wire.
Connect
one
end of
the
black
hookup
wire to
lug 1 of
switch
D
{S-1).
Connect
the other
end
of this
wire
to
hole
G on the
circuit
board
(S-1).
Position
the
wire
under
the
chassis
lip.
Prepare a 15" blue
and
a 15" black
hookup
wire. Then
form a twisted
pair
from these
two
wires'
At one
end
of
this
twisted
pair,
connect
the blue
wire
to
lug
3
(S-1)
and
the
black
wire
to
lug 2
(NS)
of
switch
D.
At the
other
end
of
the
twisted
pair,
connect
the
black
wire
to hole
F
(S-1)
and
the
bluewireto
hole
D
(S-1)
on
the
circuit
board'
Position
the
twisted
pair
under
the
chassis
lip.
Cut
each
lead of
a 10
prF
electrolytic
capacitor
to
3/4".
Connect
the
lead at the
positive
(+)
end of
the
capacitor
to
lug 2
of
switch
D
(S-2).
Connect
the
other
lead
to lug
11F of
wafer
#1
of switch
C
(S-2).
Prepare a
24"
white
hookup
wire
and a
24"
blue
hookup
wire.
Then
form a twisted
pair
from these
two
wires,
At
one
end
only
of
the
twisted
pair,
cut
off
and
discard
2"
of
white
wire.
Remove
114"
of
insulation
from the
cut
end.
Pass
this
end
of
the
twisted
pair
under
the
metal
braid
coming
from
terminal
strip
X'
Then
connect
the
white
wire
to
hole
A
{S-1)
and
the
blue
wire
to
hole
O
(S-1)
on the
circuit
board.
