DC CIRCUIT DESCRIPTION:
BTG 9 KW
GASOLINE MARINE GENERATOR SET
Safety Information
This circuit is designed and manufactured in compliance with United
States Coast Guard Standards
(33 CFR PART 183).
No modifications may
be made to it by the installer or user.
It is the installer's respon-
sibility to assure that the installation of the generator set and any
remote
start
panels
or
remote
instrument
panels
are
installed
in
compliance with the above Coast Guard Standards.
Failure to observe
these requirements could be the cause of injury.
Electrical System Characteristics
The generator
is started by a conventional,
separate cranking motor
which includes a self-contained positive-engaging starter solenoid. The
starter is internally-grounded to the engine block.
Start battery charging is accomplished through a belt-driven, 12-Volt,
35-Amp DC alternator.
Its voltage regulator is self-contained and the
alternator does not have isolation diodes.
DC voltage output is 13 -
14.5 Volts, 0 - 35 Amps.

Two panel-mounted fuses are installed to protect the starter circuit,
the running B+ circuit through the protective switches, and the remote
panel circuit.
The choke is automatic and electrically-operated.
The ignition system
is conventional, with contact points.
There is an overspeed shutdown which, when it senses engine speed at
approximately 2175 rpm, shuts off the generator set by grounding out
the
ignition
system.
This shutdown consumes 25 milliamps
(.025 or
1/40th of an Amp) at all times, once the generator is connected to its
battery.
As this only amounts to about 18 Amp-hours in a month, it is
unnecessary to be concerned with this slight discharge during normal
operation.
If
the
generator
set
were
to
be
unattended
for
many
months, stop this slight drain by turning off the main battery switch
which provides 12 Volts to the generator set.
An
optional
remote
start
panel
is
available
for
controlling
the
generator from a remote location.
Remote start panels include a green
LED which brightens at approximately 600 engine rpm.
The purpose of
the LED is to alert the operator to release the starter toggle switch;
the LED then continues indicating that the generator set is running.
