Section 2 (Generators & Regulators - Specifications): Description
WARNING: This page is about a different car, the 2000 Volvo C70 and 1999 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
Bosch generators are a conventional 3-phase, self-rectifying type. Bosch 80-amp through 120-amp generators have 14 diodes. All generators use 3 exciter diodes connected to stator windings. These diodes turn off the generator indicator light and supply power to voltage regulator while engine is running. Voltage regulator is transistorized. All models use Nippondenso generators. C70 model may be equipped with Nippondenso or Valeo model generators.
