BATTERY CHARGING SYSTEM
To test alternator before it goes to the
regulator, unplug the yellow connector
and measure the AC voltage across the
the two gray wires inside this
connector.There should be at least 20
volts AC.
CARBURETOR FUEL SOLENOID
Red wire goes to the engine plug and
then on to the positive terminal of the
solenoid to keep the battery charged.
Easiest way to check if the charging is
taking place is to measure the DC
voltage of the battery before you start the
engine. Then start the engine. Measure
the voltage at the battery with the engine
running. The voltage should be at least
one volt higher right after the engine is
started. This voltage will drop a little as
the battery gets recharged.

Gray wire goes to the engine plug,
then on to the ignition switch where it
receives power to activate the fuel shut
off valve.
