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.
11-3-4 CHECK IF THE ENGINE IS
OVERHEATED.
If the cooling air inlet andlor 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
MO,
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 MQ: the insulation is faulty and may
cause
electric leakage.
Replace the faulty part.
