Check that stator windings have no unsoldered connections, burnt areas
or grounded wìres.
Using an ohmmeter check for continuity between the red cable and the
two yellow ones.
Furthermore, check that they are insulated from the ground.
Alternator, external - 12 V, 33 A
The alternator is of the claw-pole rotor type with built-in voltage regulator.
The rotating motion is conveyed by the engine through a "V" belt and
sheave.
Features:
Rated voltage ..................... 12V
Max. current ........................ 33 A (at 7000 alternator r.p.m./min.).
RH direction of rotation.
Tighten the nut 1 at a torque of 70 Nm.
Alternator battery charger curve - external, 12 V, 33 A
The curve was obtained at room temperature of + 25°C.
Battery terminal voltage is 12.5 V.
The r.p.m. shown on the table refers to the engine.
