Electrical System and Components
Stator
The stator is mounted on the crankcase behind the
flywheel. If the stator needs to be replaced, follow the
procedures in Section 9 - "Disassembly."
Rectifier-Regulator
The rectifier-regulator is mounted on the bracket
below the overflow reservoir. See Figure 8-8. To
replace it; disconnect the connector plug and remove
the two screws. Take off the rectifier-regulator.
NOTE: When installing the rectifier-regulator, make
sure the cooling fins are "in", towards the fan.
Figure 8-8. Rectifier-Regulator.
Testing of the rectifier-regulator may be performed as
follows, using the appropriate Rectifier-Regulator
Tester (see Section 2).
To Test –
NOTE: Disconnect all electrical connections attached
to the rectifier-regulator. Testing may be
performed with the rectifier-regulator
mounted or loose. The figures show the part
removed from the engine for clarity. Repeat
the applicable test procedure two or three
times to determine the condition of the part.
15 Amp Rectifier-Regulators
1. Connect the tester ground lead (with spring
clamp) to the body of the rectifier-regulator
being tested.
2. Connect the tester red lead to the B+ terminal of
the rectifier-regulator and the two black tester
leads to the two AC terminals. See Figure 8-9.

Figure 8-9.
3. Plug the tester into the proper AC outlet/power
for tester being used. Turn on the power switch.
See Figure 8-10. The ''POWER'' light should be
illuminated and one of the four status lights may
be on as well. This does not represent the
condition of the part.
Figure 8-10.
4. Press the ''TEST'' button until a "click" is heard
and then release. See Figure 8-11. Momentarily
one of the four lights will illuminate, indicating
the condition of the part.
