Abstract
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.
