Charging circuit
How it works
1. When the engine is running, magnets attached to the
underside of the flywheel induce A.C. (Alternating
Current) in the stator that is mounted beneath the fly-
wheel. See Figure 7.20.
2. The A.C. travels from the stator to and from the regu-
lator/rectifier through the two white wires.
NOTE: The magnets inside the flywheel act as a rotor
for the charging system.
3. The regulator/rectifier takes alternating current and
converts (rectifies) it to D.C. (Direct Current). The
regulator rectifier also regulates the voltage to a nom-
inal 12 volts. See Figure 7.21.
• Actual output is closer to 14 volts, but should be
no more than 15 volts.
• To work properly, the regulator/rectifier must
have a good ground connection to the engine
block and ultimately, back to the battery negative
post.
4. Regulated D.C. power leaves the regulator/rectifier.
4a. A red wire comes out of the regulator/rectifier.
4b. The red wire changes to a red/white trace wire
at the harness connector.
