5 Ampere Alternator Charging system
1978 Johnson 55HP outboards
Description
The charging system consists of the alternator, the rectifier diodes which change the alternating current output of the alternator to direct current, and the battery itself.
The alternator is made up of two parts - the flywheel with cast-in magnets, and the stator assembly which is bolted to the crankcase. The stator assembly is made up of 8 coils wound over a laminated iron core. The flywheel turns around this assembly inducing alternating current in the coils.
The rectifier assembly converts the alternating current to direct current. The rectifier is mounted on the electrical components bracket. See Figure 7-22.
