If
the resistance reading
is
much larger or smaller than the specified value, the
DC
coil
of
the stator is
faulty.
Replace stator with a new one.

ENGINE SPEED

NOT INCREASED
WHEN A LOAD
IS
APPLIED
(1) Inspect the solenoid bracket. Check the bend
angle of solenoid bracket.
If
the bracket
is
dis-
torted, correct
the
angle with proper tool.
(2)
Check the wattage of load applied to the gen-
erator.
If
the generator is loaded over the rated
wattage, the engine speed can not be in-
creased. Most induction loads such as elec-
tric motor or electric tools or welding machine
require three to five times large wattage of their
ratings at starting. This starting wattage must
not exceed the rated output of the generator.
Check the slow set r.p.m.
The normal idling speed by the IDLE CON-
TROL is as follows
:
RGV2800
..............._..
1900 to
2100
r.p.m.
RGV4100, 61

..___...

to

r.p.m.
The
above speed setting is for
cold
engine con-
dition. If the engine speed is out
of
adjusting
range
of
the adjusting screw, move the sole-
noid backward.
