Electrical System and Components
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 backing
shroud assembly. See Figure 7-9. To replace it,
disconnect the plug, remove the two mounting
screws, and ground lead.
NOTE
: When installing the rectifier-regulator, take
note of the terminal positions and install the
plug correctly.
Figure 7-10. Connected Adapter.
2. Connect the tester ground lead (with spring
clamp) to the body of the rectifier-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 specific).
4. Connect the remaining black lead from the tester
to one of the outer AC terminals on the rectifier-
regulator. See Figure 7-11.
Figure 7-9. 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.
20/25 Amp Rectifier-Regulators
1. Connect the single lead adapter in between the
B+ (center) terminal of rectifier-regulator being
tested and the squared single end of the tandem
adapter lead. See Figure 7-10.
