Stator
1. Inspect the stator coil for continuity and check
continuity between the coil leads. If there is no
continuity, replace the stator assembly.
2. Inspect the coil ground and check continuity
between the coil and the core. If there is continuity,
replace the stator assembly.
Rectifier
1. (+) rectifier
When inspecting continuity between (+) rectifier
and stator coil lead connecting terminal using an
ohmmeter, there must have only one direction
continuity. If there is both direction continuity,
replace the rectifier assembly owing to short
circuit of diode.
2. (-) rectifier
When inspecting continuity between (-) rectifier
and stator coil lead connecting terminal using an
ohmmeter, there must have only one direction
continuity. If there is both direction continuity,
replace the rectifier assembly owing to short
circuit of diode.
Brush Replacemement
If the brush is worn out to the limit, replace the brush
as the following order.
