Ac Voltage Is Normal At No-Load, But The Load Cannot Be Applied - Robin America RGV4100 Service Manual

2-3 AC VOLTAGE IS NORMAL AT NO-LOAD, BUT THE LOAD CANNOT BE APPLIED.

2-3-1 CHECK THE ENGINE SPEED.
If the engine speed is low, adjust it to the rated r.p.m.
*Refer to Step 2-2-1 for engine speed adjustment.
2-3-2 CHECK THE TOTAL WATTAGE OF APPLIANCES CONNECTED TO THE GENERATOR.
Refer to Section 3 "RANGE OF APPLICATIONS" for the wattage of the appliances.
If the generator is overloaded, reduce the load to the rated output of the generator.
2-3-3 CHECK THE APPLIANCE FOR TROUBLE.
If the appliance is faulty, repair it.
2-3-4 CHECK IF THE ENGINE IS OVERHEATED.
If the cooling air inlet and/or cooling air outlet is
clogged with dirt, grass, chaff or other debris, re-
move it.
2-3-5 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 1MΩ, dis-
assemble the generator and check the insulation
resistance of the stator, rotor and the live parts in
the control box.
Any part where the insulation resistance is less
than 1MΩ, the insulation is faulty and may cause
electric leakage.
Replace the faulty part.
