If the insulation resistance is less than
1
M
Q
,
disassemble the generator and check the in-
sulation resistance of the stator, rotor and the
live parts in the control box. (Refer to Section
Any part where the insulation resistance is less
than 1 M SZ
,
the insulation is faulty and may
cause electric leakage.
