Alternators - S.E.V. MOTOROLA: Description

SEV Motorola alternators are conventional three-phase, self-rectifying type alternators. Six silicon diodes (three positive and three negative) are used to rectify AC current. The 55 ampere unit incorporates two isolation diodes, connected in parallel, which are mounted on the exterior. Isolation diodes have two functions: They prevent battery from discharging through regulator and alternator field, and they provide a simple means of operating charge warning lamp.
