FORD MODEL T (1923-24-25-26) FORD GENERATING, STARTING AND LIGHTING SYTSEM FORD IGNITION BATTERY.—Ford or U. S. L. Type 3-HVX-5X, 6 volt. The starting capacity is 105 amperes for 20 minutes. Lighting capacity is 5 amperes for 18.4 hours. The negative (—) terminal is sibtated, IGNITION:—The magneto is carried in the flywheel housing. There should be a clearance of .031 inch, between the coil cores and the magnet pole pieces. The magneto delivers alternating current to four vibrator ignition ode one connected to each spark plug, as the timer closes the circuit in the proper sequence. When the vibrator arm is held down, the contacts should separate .030 inch. If the contacts are badly burned or pitted resurface with a fine flat jeweler’s file or on a medium hard oilstone. Coils should be adjusted to draw 1-3 amperes at 6 volts. iling:—Put several drops of light engine oil in the spring oiler of the timer every two weeks. In cold weather a mixture of 14 kerosene and 3% light engine oil should be used. Timing:—Timer roller should just make connection with segment connected to Num- ber | coil when the piston in Number | cylinder is on top dead center of the power stroke, spark control lever and timer housing in the fully retarded position. Firing Order:—The firing order is 1-2-4-3. Spark Plug Gaps:—The spark plug gaps are .030 to .032 inch. STARTER:—Type F.A. Starter is connected to the engine through a Bendix drive. The direction of rotation is counter-clockwise, looking at the commutator end. Starter cranks engine at 150 R.P.M., taking 160 amperes at 5 volts. hed QP, !Retay iz Starter Data—F.A. 8 Torque R.P.M.

Generator current regulation is by the third brush system. Direction of rotation is counter-clockwise, looking at the commutator end. Generator Data—F.A. SS See | -l e, GS Visciscceees oc onc eceensccccazel 2000 LIGHTING AND IGNITION SWITCH Charging rate is varied by adjustment of the third brush setting. Loosen the clamp 4, nut holding the third brush holder. Move third brush in the direction of armature rotation to increase the charging rate, or in the opposite direction to decrease the leo charging rate. Clamp the third brush after position adjustment. The generator fields draw 2.4 amperes at 6 volts. Oiling:—Put 4 or 5 drops of light engine oil in the rear generator bearing oiler se every two weeks. If the car is driven more than 500 miles in 2 weeks, the oiling must be done every 500 miles. . le © RELAY:—Relay is mounted on the generator frame. Relay closes at 600-650 R.P.M. of armature or 8-10 miles per hour, and opens at 550- .P.M. of armature as or 6-8 miles per hour, the discharge current being 0-2 amperes. Relay contacts . separate .032 inch. If badly burned or pitted resurface with worn No. 00 sand- paper. Remove all grit. Adjust before again putting into service. <> LAMPS:—Head lamps are 6-8 volt, 21 cp. Dimmer and tail lamps are 6-8 volt, 2 cp.
