AJAX AFTER APRIL FIRST (1926) AUTO-LITE GENERATING, STARTING AND LIGHTING SYSTEM AUTO.-LITE IGNITION BATTERY:—U.S.L. Type 3-HVX-5X, 6 volt. The negative (—) terminal is grounded. The starting capacity is 105 amperes for 20 minutes. Lighting capacity is 5 amperes for 18.4 hours. The battery is 7 7/16 by 9% by 9% inches. IGNITION :—Coil Model IG-4065. Distributor Model IG-4110. Breaker contacts separate .020 inch. They are made of tungsten. When the condition of the contacts affects the ignition, remove and resurface with a fine, flat jeweler’s file. The surface of the contacts should be flat and parallel. The distrib- utor is of the full automatic type. Automatic advance begins at 200 R.P.M. of the distributor and reaches a maximum of 15° (distributor) at 1200 R.P.M. This is equivalent to a flywheel advance of 30° at 2400 R.P.M. of the engine. Oiling:—Refill the grease cup under the distributor head with medium cup grease and turn down one turn every two weeks. Put one drop of light en- gine oil on the breaker arm hinge and place a small amount of vaseline on the face of the breaker cam every month or each 1000 miles if the car is driven more than 1000 miles in a month. Timing:—Breaker contacts begin to separate when piston entering power stroke reaches top dead center with the breaker assembly in the fully re- tarded position. Firing Order:—The firing order is 1-5-3-6-2-4, Spark Plugs:—Spark plug diameters are 7% inch. Gaps are .025 inch. STARTER:—Model MN-4108. Starter is connected to the engine through a Ben- dix drive. The direction of rotation is counter-clockwise, looking at the commutator end. Starter cranks the engine at 184 R.P.M. taking 160 am- peres at 4.7 volts. Starter brush tension should be 114-142 pounds. Starter Data Torque R.P.M. Volts Amperes ph Vena ti i a 45 (Without Bendix) 115 “ Oiling:—Put 4 or 5 drops of light engine oil in oiler on the drive end of the Starter every month or each 1000 miles if the car is driven more than 1000 miles in a month. The commutator end bearing is of the self-lubricating type and requires no attention. GENERATOR:—Model GYA-4201. The direction of rotation is counter-clockwise, looking at the commutator end. Generator current regulation is by the third brush system. To adjust generator output, remove the commutator cover band and shift the third brush mounting bracket by tapping the third brush mounting stud with a screwdriver. Shifting the third brush in a counter-clockwise direction increases the charging rate and in the oppo- site direction decreases the charging rate. The mounting bracket is held in any desired position by friction between the third brush mounting stud and the generator end plate. DISTRIBUTOR AJAX AFTER APRIL FIRST (1926) AUTO-LITE GENERATING, STARTING AND LIGHTING SYSTEM AUTO-LITE IGNITION Generator Data Cold Test Hot Test Volts R.P.M. Amperes Volts Motoring freely, generator draws 5 amperes at 6 volts. Shunt field current is 3.8 amperes at 6.2 volts. Generator brush spring tension is 1144-144 pounds each. Oiling:—Put 3 or 4 drops of light engine oil in each of the generator bearing oilers every two weeks or each 500 miles if the car is driven more than 500 miles in two weeks. RELAY :—Model CB-4007. Relay is mounted on top of the generator. Relay con- tacts close when the voltage of the generator reaches 17-7.5 volts and open with a discharge current of .5-2.5 amperes. Contacts separate .025-.035 inch. Air gap between relay armature and coil core is .010-.030 inch, contacts closed. LIGHTING:—Switch B & S Type 39890. Head lamps are each 6-8 volt, 21 cp. double filament using second 21 cp. filament for dimming. Dash lamp is 6-8 volt, 2 cp. S.C. Dome lamp is 6-8 volt, 4 cp. 8.C. Side and tail lamps are each 6-8 volt, 3 cp. S.C. FUSES:—Generator field fuse is 5 ampere.
