Alternator & Regulator: Description

Metro models built in Japan (VIN J) are equipped with a Nippondenso 50 amp alternator with internal regulator. Metro models built in Canada (VIN 2) are equipped with a Mitsubishi 55 amp with internal regulator. Both alternators are serviceable and can be repaired or overhauled.

The Integrated Circuit (IC) regulator is a solid state unit mounted inside alternator to rear end frame. Voltage regulator voltage cannot be adjusted.

Two brushes carry current through 2 slip rings to field coil mounted on rotor. Stator windings are assembled inside a laminated core forming part of alternator drive and frame assemblies. A rectifier bridge containing 6 diodes is connected to stator windings.
