A bridge rectifier, known as the rotating rectifier assembly, is mounted within the rotor. Neither brushes nor slip rings are used, which reduces the quantity of wearing parts. The most crucial alternator provides a rotating area as explained previously mentioned and a stationary armature (electrical power technology windings).

To ease obtain of the tinware screws remove this tube and have it out of the way in which. FI models utilize a pastic tube while carb styles use corrugated paper hose.
