Figure 8-23. 3 Amp/70 Watt Stator.
Stator
The stator is mounted on the crankcase behind the
flywheel. Follow the procedures in Section 9 -
“Disassembly” and Section 11 - “Reassembly” if stator
replacement is necessary.
Rectifier-Regulator
The rectifier-regulator is mounted on the blower
housing. See Figure 8-24. To replace it, disconnect the
plug(s), remove the two mounting screws, and ground
wire or metal grounding strap.
NOTE: When installing the rectifier-regulator, take
note of the terminal markings and install the
plug(s) accordingly.
Figure 8-24. 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 8-25.
