Stator
The stator is mounted on the crankcase behind
the fl ywheel. Follow the procedures in Section 9 -
Disassembly and Section 11 - Reassembly if stator
replacement is necessary.
Rectifi er-Regulator
The rectifi er-regulator is mounted on the backing
shroud assembly. See Figure 7-16. To replace it,
disconnect the plug, remove the two mounting
screws, and ground lead.
NOTE: When installing the rectifi er-regulator, take
note of the terminal positions and install the
plug correctly.

Testing of the rectifi er-regulator may be performed as
follows, using the appropriate Rectifi er-Regulator
Tester (see Section 2).
To Test –
NOTE: Disconnect all electrical connections a ached
to the rectifi er-regulator. Testing may be
performed with the rectifi er-regulator
mounted or loose. The fi gures 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.
20/25 Amp Rectifi er-Regulators
1. Connect the single lead adapter in between the
B+ (center) terminal of rectifi er-regulator being
tested and the squared single end of the tandem
adapter lead. See Figure 7-17.
Figure 7-17. Connected Adapter.
2. Connect the tester ground lead (with spring
clamp) to the body of the rectifi er-regulator.
3. Connect the red lead and one of the black leads
to the pair of terminals on the open end of
the tandem adapter lead (connections are not
location specifi c).
4. Connect the remaining black lead from the tester
to one of the outer AC terminals on the rectifi er-
regulator. See Figure 7-18.
