ELECTRICAL SYSTEM

Control Circuit
The engine that drives the generator end has a 12-Volt DC electrical control circuit, as shown on the wiring
diagrams which follow on pages 22 and 23. Refer
to
these diagrams when troubleshooting
or
servicing
electrical components on the engine.
CAUTION
To avoid damaging the battery's charging circuit, never shut off the engine's battery switch
while the engine is running.
However, shut off the engine's battery switch
to
avoid electrical shorts when working on the
engine's electrical circuit.
Battery Specification
The minimum recommended capacity of the battery used in the engine's 12-Volt DC control circuit is
125 Ampere-Hours (minimum) for the generator set covered
by
this manual.

CAUTION
When quick-charging the battery with an external charger, be sure
to
disconnect the battery
cables from the battery. Leaving the charging circuit connected while quick-charging will
damage the alternator's diodes.

CAUTION
When testing the alternator circuit (charging circuit),
do
not use a high-voltage tester such as

When operating the generator,
do
not disconnect the positive battery terminal from the B ter-

Incorrect fuel injection timing will result in hard engine starting and poor engine performance. Adjust the injection timing as follows:
1. Locate the timing pointer on the front gear
cover. This pointer is located at about the
10:00 o'clock position when viewing the
front crankshaft pulley.
2. The front crankshaft pulley has timing marks
