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 1MΩ, 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 1MΩ, the insulation is faulty and may cause electric leakage.

Replace the faulty part.
