| | | | | | { | | | Chandler Light Six (1917-18) (Serial Nos. 35,001 and up) Gray and Davis Generating, Starting and Lighting System Bosch Magneto Ignition Battery.—Battery is 6 volt, 80 ampere-hour. The positive (+) terminal is grounded. Ignition.—Breaker contacts separate .014 inch to .016 inch. When the condition of the points affects the ignition, resurface with a fine, flat jeweler’s file or worn No. 00 sand paper. Oiling.—Put 2 or 3 drops of light machine oil in magneto oilers every month. If car is driven more than 1000 miles in a month, the oiling must be done every 1000 miles. Timing.—Breaker contacts separate when 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 |, 5, 3, 6, 2, 4. Spark Plug Gaps.—Spark plug gaps are .026 inch. Starter.—Starting motor is No. 126. It js connected to the engine through a Bendix drive. Operating freely, starter takes 35 amperes at 3 volts, and runs at 2200 R.P.M. With the same current startec runs at 4500 R. P. M., with 5.5 volts, and at 5000 R. P. M., with 6 volts. The torque is 1.5 pound-feet at 1660 R. P. M., taking 100 amperes at 5.75 volts. Pressure of motor brushes on commutator is 214 pounds. Oiling.—Put 4 or 5 drops of light engine oil in each of the starter bearing oilers every month. Generator.—Generator current regulation is by third brush system. Generator Data, Type No. 400 R. P.M.

Rotation is counter-clockwise, looking at commutator end. Position of third brush is adjustable by means of a rack and pinion movement operated by turning a screw, accessible through an opening in the end plate. Tum the screw to the right to increase the charging rate and to the left to decrease the charging rate. Oiling.—Put 5 or 6 drops of light engine oil in each of the generator oilers every two weeks. If car is driven more than 500 miles in two weeks, the oiling must be done every 500 miles. Relay.—Relay closes at 7 miles per hour and opens at 5 miles per hour. Charging current is | to 3 amperes at closing, and discharge current 0 to 2 amperes at opening of relay contacts. Contacts separate .015 inch. Minimum air gap between armature (moving member) and coil core is .020 inch. Clean relay contacts by drawing unglazed paper between them. If badly burned or pitted, resurface with well wom No. 00 sand paper. Remove all grit. Adjust before again putting into service. Lamps.—Head lamps are 6-8 volt, 18 cp. Dimmer lamps are 6-8 volt, 4 cp. Dash lamp is 6-8 volt, 4 cp. Tail lamp is 6-8 volt, 2 cp. Fuses.—Fuses are 20 ampere.
