Beginning with the 1983 Camry, a compact, highspeed alternator with a built-in IC regulator is used on Toyota vehicles. Corolla models with the 4A-C engine use a different alternator with an integral IC regulator.
This new alternator is compact and lightweight. It provides better performance, as well as improved warning functions. If either the regulator sensor (terminal "S") or the alternator output (terminal "B") become disconnected, the warning lamp goes on. It also provides better serviceability. The rectifier, brush holder, and IC regulator are bolted onto the end frame.
