MARINE ENGINE ELECTRICAL SYSTEM
ACTIVATION BY KEY SWITCH
This system is supplied on most Wester-
beke engi nes begi nni ng r~ay. 1980. Essen-
tially activation of the circuit is
accomplished by the ignition position of
the
key switch. No oil pressure switch
is required.
The engine is preheated
by depressing the preheat push button.
The engine is cranked by turning the
key switch to the right-most momentary
position.
Voltage is maintained to the instruments,
fuel solenoid or fuel
lift pump if sup-
plied,
and to other electrical devices via
the ignition position of the
key switch.
Models which have a fuel solenoid or elec-
tric fuel pump may be turned off via the
key switch. Models with mechanical fuel
lift pumps or no fuel solenoid are stopped
by pulling a stop cable.
The circuit is protected by a circuit
breaker located near the starter. Any
time excessive current flows, the circuit
breaker will trip. This is a manually
resettable breaker, and must be reset
before the engine will operate
electrically
again.
CAUTION - the builder/owner must ensure
that the instrument panel, wiring and
engine are installed so that electrical
devices cannot come in contact with sea-
water.
The latest information regarding your
engine1s
electrical system is included
on the wiring diagram shipped with the
engine.
Be sure to study this wiring
diagram and all the notes thereon.
