and must have the knowledge and skill to keep the automobiles electrical system in working order that the spark to fire the engine it would be no power in the early days electrical energy was supplied by dry batteries but the car of today it carries its own generating and storage plants the storage battery is of low voltage so a call and condenser is necessary to step up the current enough to jump the spark gaps in the spark plugs the problem distributor also must be tested and kept in proper working order besides the ignition system the lighting and starting circuits would sometimes need the services of a competent mechanic the use of heaters windshield wipers and radios has further increased and complicated the electrical work  serviceman because of the high speed at which vehicles travel today that care and adjustment of brakes is a serious and vital part of the serviceman's work the safety of the car on the highway largely depends on good brakes along with in the larger garages the man who becomes expert in servicing engines may find specialized work on engines only body and fender shop which employ men who are specialists in that line battery and electrical shops and other caps which make brake testing and whe the principal brought to their business or any of these jobs training in general service work is valuable there is an opportunity in the larger garages for the serviceman to advance to service manager or to become a troubleshooter besides technical knowledge and skills these jobs require the ability to meet the public to make a good impression and to
