‡ For the engine to start:
‡ The
Key Switch S1
must provide positive voltage to the
START
relay coil
K3
and the
IGN
relay coil
K2
.
‡ The
K2 RELA CONTROL SWITCH
must be closed to provide a ground to the
IGN
relay coil
K2
. This closes
the

to the
K2 RELA CONTROL SWITCH
to open the switch, no ground will
be provided to the

, the
K2
contacts will not close and no positive voltage will be sent to
the
IGN SW INPUT
.
‡ The
K3 RELA CONTROL SWITCH
must be closed to provide a ground to the
START
relay coil
K3
. This
closes the
K3
relay contacts to provide positive voltage to the
