ELECTRIC STARTING AND LIGHTING SERVICE
The Occupation
The principal parts of an electric starting and lighting system are the electric starting motor, the electric generator, and the storage battery. The work of the expert in this division consists of the repair, adjustment, care, operation, and installation of these systems and auxiliary parts, but usually not including the storage battery which requires the individual attention of another specialist.
To keep the starting motor in good running condition the expert must be able to remedy grounds, short circuits, and commutator and brush troubles. The generator and all connecting parts must be kept clean in order to insure reliable action. There are many types and varying features in generators, motors, auxiliary devices, and wiring circuits, with which the mechanic must be familiar. Automobile manufacturers in altering the characteristics of their motors from year to year and manufacturers of electrical apparatus in introducing various improvements may entirely change their systems.
In addition to being able to locate trouble by tracing and testing systems for grounds, shorts, and breaks in wiring, it is necessary for the mechanic to install systems including all the wiring. He must be able to repair and keep in shape electric horns and gear shifts which are closely related to the starting and lighting systems. The wiring for starting, generating, and lighting systems involves the installation of all necessary wires, many of which must be run in conduit. It also includes the use of proper sized wire and their connection to the lights, starter, horn, fuse boxes, switches, generator, and battery. The repair and adjustment of the lighting system require considerable expert attention, as does also equipment of cars with lamp reflectors, measuring instruments, and other devices.
Tools and Equipment
All tools used in the maintenance and service of automobile starting and lighting systems are small and light. They will include screw drivers, wrenches, hammers, files, pliers, and various drilling tools. Some machines may be required to make or fit metal parts, but as a rule they will be found in the repair shop.
