GENERATOR CONSTRUCTION[LF, L3]

European (L.H.D. U.K.) Specs.

• With the elimination of the voltage regulator, generator control is carried out by the PCM. Excitation current in the field coil is increased or decreased by the duty signal from the PCM sent to the power transistor built into the generator. (See GENERATOR CONTROL OPERATION[LF, L3].)

• Two delta connection type stator coils have been adopted.

• A generator duct and a generator heat insulator made of plastic have been adopted to protect the generator from the exhaust manifold heat.

• The phase difference in the circuit of the two stator coils causes the electromagnetic pull between the rotor and the stator to be eliminated logically. Due to this, electromagnetic vibration and generator operation noise (electromagnetic noise) have been reduced.

Phase difference

• The pulsation occurring through voltage rectifying is minimized, as a result, stable voltage output is supplied due to the adoption of two stator coils with the phase difference.

• The generator warning light in the instrument cluster illuminates under the following conditions. (See DTC DETECTION LOGIC AND CONDITIONS[LF, L3].)

― Charging system voltage problem

― Charging system voltage low

― Charging system voltage high

― IAT sensor circuit low input

― IAT sensor circuit high input
