DURANT MODEL 55 (1928) SERIAL NUMBERS 1000 UP CONTINENTAL 14L ENGINE AUTO-LITE GENERATING, STARTING SYSTEM AUTO-LITE IGNITION BATTERY:—U.S.L., Type 3-CVX-5X7, 6 volt, 11 plates. The negative (—) terminal is grounded. Starting capacity (20 minute rate) is 96 amperes for 20 minutes. Lighting capacity (5 ampere rate) is 5 amperes for 16.8 hours. Battery is mount- ed under front floor boards on right frame member. IGNITION:—Coil Model {G-4066. Coil is mounted on the Ignition current is 1.5-2 amperes at 6 volts with engine running an the engine. t 9-5 amperes at 6 volts with engine stopped. Distributor Model IG-4067-A. Breaker contacts separate .020-.025 inch.

The direction of rotation is counter-clockwise, look- ing at the commutator end. Generator current regulation is by third brush shunt freld. To adjust generator output, remove commutator cover band and shift third brush and mounting bracket by tapping on mounting stud with a screwdriver. Shift the third brush in a counter-clockwise direction to increase the charging rate and in the opposite direction to decrease the charging rate. The third brush is held in any position by friction between the mounting stud and the end plate. With standard car setting the maximum charging rate is 14 amperes (cold) reached at 1450 R.P.M. or 25 miles per hour. Generator Data Amperes Volts R.P.M ee eee eee 6.4 cscscvececcenccl | Sell.
