5.
Unsolder the stator
coil
lead
wires.
Remove
the stator
assembly.
CAUTION
Never
heat
the
lead
wires long to
prevent
damage to diodes.
6.
Disconnect the capacitor from terminal
liB.

7.
Loosen
the screws fixing the rectifier
and
remove
the rectifier.

Wear and roughness
a.
Connect a circuit tester
(ohmmeter)
across the
lead
wire
and
case
of the diode to
be
tested.
The
diode
is
considered
normal
if its
resistance
is
large
in
either direction
and
small
in
the
reverse
direction.
b.
If there
is
equal
resistance
in
both directions, the diode
is
suspected to
be
defective.
Replace
the rectifier
assembly.
c.
Check
every
diode for conduction.
