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

to

wire

(C841)

is

turned

against

(connection

between

When

the

ignition/starter

key

is

released,

the

contact/starter

switch

automatically

springs

back

and

remains

in

the

“contact”

position.
