CHEVROLET MODEL D, 8 CYLINDER (1917-18) AUTO-LITE GENERATING, STARTING AND LIGHTING SYSTEM REMY IGNITION This Page Applies to First 1000 Cars BATTERY.—Battery is 6 volt, 115 ampere-hour. The negative (—) terminal is grounded at the starting motor. ; IGNITION.—Breaker contacts separate .020 to .025 inch. When condition of contacts affects the ignition, resurface with a fine flat jeweler’s file or worn No. 00 sandpaper. OILING.—Refill the cup under the distributor head with soft cup grease and turn down two turns every two weeks. At the same time put a small amount of vaseline on the fiber bumper of the contact arm, using a toothpick. If the car is driven more than 500 miles in two weeks, these attentions should be given every 500 miles. TIMING.—Breaker contacts begin to separate v:hen the piston entering power stroke is on top dead center, spark control lever and breaker assembly in the fully retarded position, FIRING ORDER.—The firing order is 1R, 4L, 2R, 3L, 4R, IL, 3R, 2L. SPARK PLUG GAPS.—Spark plug gaps are .025 inch to .030 inch. STARTER.—Model ME.

Shunt field current is 1.7 amperes. OILING.—Put several drops of light engine oil in each of generator oilers every two weeks. If car is driven more than 500 miles in two weeks, oiling must be done every 500 miles. RELAY.—Relay closes at 8-10 miles per hour or 550-600 R.P.M. of armature and opens at 5-8 miles per hour or 450-500 R.P.M. of armature. Charging current is .5 to 1.5 amperes at closing and the discharge current, 0-1 ampere at opening of relay. Clean relay contacts by drawing unglazed paper between them. If badly burned or pitted, resurface with well worn No. 00 sandpaper. Remove all grit. Adjust before again putting into service. LAMPS.—Head lamps are 6-8 volt, 15 cp. Dimmer lamps are 6-8 volt, 4ep.
