Operational Problems and Maintenance of AC Generator (Alternator) Charging Systems 630155

Semiconductors (diodes and transistors) are contributing considerably toward minimizing operational problems in today's automotive electrical systems. However, because of their polarity-sensitive characteristic, maintenance personnel need to know more about the procedures involved in servicing the various components. This paper discusses diode-rectified generators, their companion regulators, charging system circuitry, and testing procedures involved. Included is an explanation on the differences between the d-c and a-c systems, maintenance checks common to both, basic information pertaining to on-the-vehicle testing, and a general outline covering the individual testing procedures.
