Summary
This chapter has presented information and procedures in troubleshooting electrical
systems. You covered the alternator and its components and function, along with
rectifiers, voltage regulators, and troubleshooting procedures.
The succeeding topics encompassed troubleshooting the cranking system with
emphasis on the various tests, the ignition system and its components and subsystems,
lighting systems, and electrical accessories.
Electric and electronic devices can be found almost everywhere on an automobile,
truck, power generation equipment, and construction equipment. These components
have even replaced some mechanical devices. They are more efficient, compact, and
lighter.
Troubleshooting equipment takes complex diagnostic procedures, much service
literature, and specialized equipment. It is uncommon for the mechanic to get through
even one day without referring to a service manual or technical literature.
Specialized tools, test equipment, and other diagnostic equipment, as well as service
manuals and technical literature, are rapidly becoming a necessary requirement.
