provide
a
constant
voltage
at
pins
1

2
of
connector
705
on
the
P
CB.
This
provides
“voltage

for
the

When
the
ignition/starter
switch
(C841)
is
set
to
the
“contact”
position
(connection
between
points
1
and
4),
relay
G015
is
energised
via
wire
4001.
This
then
connects
wire
1000
(voltage
before
contact)
to
wire
1010
(voltage
after
contact).
When
the
ignition/starter
switch
(C841)
is
turned
against
the
spring
pressure
(connection
between
points
1
and
2),
relay
G015
remains
activated.
When
the
ignition/starter
key
is
released,
the
contact/starter
switch
automatically
springs
back
and
remains
in
the
“contact”
position.
