Mounted on the stator housing are four spring-loaded carbon brushes which contact the armature commutator.Ĭomponents of the control system are the switch box assembly (containing voltage regulator, cutout relay and starter solenoid), two micro-switches (3,7) and a keyswitch (1). Six alternate field pole shoes of the stator are series-wound with heavy gauge wire for starting the other six carry lighter gauge shunt field windings for generating power. Main components of the starter-generator unit are the field stator with 12 radial field coils, and the bell-shaped armature rotor with the commutator formed on its inner vertical face The armature is mounted directly on the engine crankshaft end taper (right side) and rotates at engine speed. Ignition spark is produced by a 12-volt coil through a cam operated circuit breaker with built-in automatic advance mechanism. The Harley Davidson gasoline cart has a 12-volt electrical system utilizing a combination starter motor/generator unit built into the engine crankcase, in conjunction with a control switch-box-regulator unit and a storage battery using a negative grounded system.
