Alternator & Regulator: Description
The Nippondenso alternator uses 4 positive and 4 negative diodes to rectify current. A voltage regulator, which is part of the alternator, controls charging system voltage.
Charging system incorporates Electric Load Detector (ELD), which measures load on the charging system. ELD sends signal to PGM-FI ECM, which controls voltage regulator. By adjusting voltage needs, PGM-FI ECM reduces mechanical load on engine for greater fuel economy.
