PLAN No. 1153. AUTOMOBILE IGNITION SERVICE

Occupation

The ignition system is usually made up of certain electrical devices which probably give more trouble to the auto man and require more expert attention than all the other parts on the automobile. To be able to diagnose a case and submit a remedy for ignition troubles, it is necessary to be thoroughly familiar with the principles of ignition and to understand how these ignition systems are operated and maintained. Ignition primarily means igniting the gas in the cylinders of an engine by means of an electric spark as the gas mixture is compressed. An ignition expert should first of all have a practical knowledge of electricity, know the meaning of electrical terms and the method of generation and transmission of electric current. Of the two systems of ignition, high and low tension, the high-tension system is now in use in nearly all makes of motor cars. The low-tension system was formerly used to a great extent on boat engines, and is used now to some extent on stationary engines.

The ignition mechanic deals with the testing, adjustment, and maintenance of current supply, vibrators, coils, commutators and timers, contact breakers, spark plugs, condensers, distributors, magnetos, and connectors. He must be thoroughly familiar with wiring systems and their connections. Spark plugs will have to be cleaned, adjusted and repaired, as will the vibrators when they are used. Ignition timing to insure ignition at the right time requires special attention. The care, installation, and maintenance of magnetos, which brings in the proper firing order of the engine, care of the distributor, and attention to connections, is one part of the ignition expert’s task. The field of ignition trouble may be covered under three heads: (1) Failure of current supply, (2) short circuits or grounds, (3) failure of ignition devices. To keep the ignition system in good working order it is necessary to locate trouble and make repairs as indicated.

Tools and Equipment

Because of the many small and complex parts ignition systems require delicate attention. This involves the use of small hand tools only, such as will be used by the electric starting and lighting experts. Although it will be necessary to make certain repairs to broken and worn parts, it is customary to replace with new parts.

Disabilities

The work of the ignition expert is very much like the work of the electric starting and lighting expert. Bench repairs to magnetos and other devices can be made by a man whose disability requires him to sit. The work is not strenuous and consequently could be done by men with lung disease, hernia, and abdominal troubles, except where it is necessary to stoop or bend over the job, as would be necessary in testing for trouble and making connections in the installed system.

Because of the delicate work, a mechanic’s eyesight must be good, but poor hearing would not debar a man from this occupation. It is quite necessary for the workman to have good use of his hands and fingers.

Previous Training and Experience

The same training and experience helpful to the electric starting and lighting expert would aid the man in training for ignition work. A man who has been employed previous to army service in any electric work, such as telephone and telegraph installation and maintenance, or the making of electric motors and devices, would have acquired electrical experience which would be of great help to him in this work.

Where and What Education Will Be Given

The classes for ignition mechanics will be carried on in both schools and shops. The time will probably be divided between theory and shop practice. The proper equipment and practical jobs will be available for teaching the man to do the work.

The course will be from four to six months in length for about seven hours per day for five days in the week. Instruction will include all problems requiring attention of the commercial ignition shop.

After the Training—What?

The demand for the ignition expert is equally as great as for any other automobile specialist. His services are required in garages and service stations, as well as in assembly plants, and in the driving and operation of motor cars and trucks. The hours of employment are the same as in other auto repair shops, usually eight hours per day for union shops, and longer in small unorganized shops and where the mechanic owns his business.

The prevailing wage is 60 cents per hour, although this may vary from 30 cents to 75 cents per hour, depending upon labor conditions and methods of employment. It is probable that ignition experts will be employed only in the larger places, but it is necessary to have expert ignition service in any shop. This is in small shops usually taken care of by the repair-shop mechanic who has a general knowledge of the automobile maintenance and service. Employment for the trained man will be stable. Ordinarily only the better class of mechanics, those with special training are retained during the winter season, when the overhauling of cars is done. The rush season from spring to fall gives employment to a number of “roustabouts” or helpers, but these “floaters” require no special training.

Promotion and success will depend largely upon the ability of the mechanic, but it is possible for him to advance to positions of responsibility, carrying increase of wages. The field is large and skilled mechanics are scarce, thus making it possible for the trained man to find suitable employment and to make changes for promotion.
