1)
Use multimeter to test resistance of windings. Resistance should be
0.5 to 1.1 R.
2)
Use multi meter to test resistance to ground. Resistance should be infinite.

The charging system supplies electrical devices and also charges the battery while the
engine runs. It consists of a Permanent Magnet Alternator (PMA) and a Regulator.
1.
This permanent magnet alternator (PMA) is a 12 pole 3 phase rotating magnet
type generator. It is a simple construction consisting of a stator and rotor.
The rotor is made up of permanent magnets, alternator body and magnet retainer
mounted on the flywheel.
The stator has 12 poles with coils and is mounted on the rear plate the stator goes
inside the rotor.
2.
Later engines use a single phase alternator of similar construction and a single
phase regulator.
