Theory of Operation:
The charging system is of the permanent magnet and
stator design. Magnets imbedded into the crankshaft
flywheel pass a multi-pole stator mounted under the
flywheel, inducing alternating current into the stator
coils. Alternating current is routed to the headlamp
bulbs anytime the engine is running through the 451
Yel/Wht wire. One half of the stator output current is
rectified by an in-line diode in the 220 Red/Blk circuit,
and used to charge the battery. Charging output is un-
regulated.
