General
This manually-controlled series of
Westerbeke marine diesel gener-
ators is equipped with toggle
switches on the engine's control
panel and, optionally, at remote
panels. The following instructions
and methods of correcting minor
problems apply only to such tog-
gle switch controls.
All three switches are momentary
contact type and serve the follow-
ing functions:
1.
PREHEAT: The PREHEAT tog-
gle switch is a double-pole,
single-throw switch. The switch
serves two purposes: preheat-
ing the engine for easy starting
and defeating or bypassing the
engine's protective oil pressure
sensor.

turns on the fuel solenoid, instrument power, alternator excitation and provides power to the START switch.
2.
SIABI:
The STARTtoggle switch is a double-pole, single-throw switch. The switch, when activated, ener-
gizes the starter solenoid for starting the engine. This switch will not operate electrically unless the
PREHEAT switch is depressed and held at the same time.
3..sIQE.: The STOP toggle switch is a single-pole, single-throw, normally-closed switch. This switch
provides power to the fuel solenoid, instrument cluster and alternator excitation, after the oil pressure
switch has closed upon starting. Opening of this switch opens the power circuit to the fuel solenoid, thus
stopping the flow of fuel to the engine and stopping the engine.
4. In addition to the three switches above, the Standard Instrument Panel used with Westerbeke diesel gen-
erator sets includes two gauges, which indicate water temperature in degrees Fahrenheit (WATER
0
F)
and oil pressure in pounds per square inch (OIL PSI), and two meters, which indicate DC control circuit
voltage (VOLTS) and generator running time (ELAPSED TIME) in HOURS and
1/10
hours. The Water
Temperature and Oil Pressure gauges, and the DC Voltmeter are illuminated; the ELAPSED TIME meter
is not.
