The starting motor is lubricated by the Ford splash system, the same as the engine and transmission. The generator is lubricated by a splash of oil from the time gears. In addition an oil cup is located at the end of the generator housing and a few drops of oil should be applied occasionally.

The introduction of a battery current into the magneto will discharge the magnets and whenever working on the ignition system or wiring do not fail to disconnect the positive wire from the battery. The end of this wire should be wound with tape to prevent its coming in contact with the terminal again.

The ammeter is located on the instrument board. This indicator registers "charge" when the generator is charging the battery and "discharge" when the lights are burning and the engine not running above 10 miles per hour. At an engine speed of 15 miles per hour or more the ammeter should show a reading of from 10 to 12. If the engine is running above 15 miles per hour and the ammeter does not show a proper reading, first inspect the terminal posts on the ammeter, making sure that the connections are tight, then disconnect the wire from the terminal on generator, and with the engine running at a moderate speed, take a pair of pliers or a screw-driver and short-circuit the terminal stud on the generator to the generator housing. If the generator is O. K., a good live spark will be noted. (Do not run the engine any longer than is necessary with the terminal wire disconnected.) Next inspect the wiring from the generator through the ammeter, to the battery for a break in the insulation that would result in a short-circuit. If the trouble is not located, then remove the dust cap from the end of generator and thoroughly clean the generator commutator, using for this work a fine grade of sandpaper which has been slightly oiled. With the motor running hold the sandpaper against the commutator with the fingers until all dirt has been removed and a bright surface attained.

The lighting system consists of two headlights and a tail light operated by a combination lighting and ignition switch located on the instrument board. The headlamp bulbs are of 6-8 volt, double filament type. The major filament is 18 candle-power, and the minor filament is 2¾ candle-power. The small bulb used in the tail light is of 6-8 volt, single contact, two candle-power type. All of the lamps are connected in parallel so that the burning out or removal of any one of them will not affect the other. Current for the lamps is supplied by the battery. Do not connect the lights to the magneto as it will result in burning out the bulbs and might discharge the magnets. Cut No. 23 shows the different circuits and the course of the current.

If either the starter or generator fails to give proper service, the owner should at once consult an authorized Ford dealer. Owners should not attempt to repair or adjust the mechanism of the starter and generator.
