11-3 AC VOLTAGE
IS
NORMAL AT NO-LOAD, BUT THE LOAD CANNOT BE APPLIED.
11-3-1 CHECK THE ENGINE SPEED.
If the engine speed is low, adjust it to the rated r.p.m.
*
Refer to Step 11-2-1 for engine speed adjustment.
11-3-2 CHECK THE TOTAL WATTAGE
OF
APPLIANCES CONNECTED TO THE GENERATOR.
Refer
to
Section
7
"RANGE
OF
APPLICATIONS" for the wattage of the appliances.
If the generator
is
over-loaded, reduce the load to the rated output
of
the generator.
11-3-3 CHECK THE APPLIANCE
FOR
TROUBLE.
If the appliance is faulty, repair it.
11-34 CHECK
IF
THE ENGINE
IS
OVER-
HEATED.
If the cooling air inlet and/or cooling air outlet is
clogged with dirt, grass, chaff or other debris..
remove it.
11-3-5 CHECK THE INSULATION
OF
THE
GENERATOR.
Stop the engine. Measure the insulation resistance
between- the live terminal of the receptacle and
the ground terminal.
If
the insulation resistance is less than
1
MQ:
dis-
assemble the generator and check the insulation
resistance
of
the stator, rotor and the live parts
in
the control box. (Refer to Section
8-3.)
Any part where the insulation resistance
is
less
than
1
ME,
the insulation is faulty
and
may cause
electric leakage.
Replace the faulty part.
