The generator for the 1948 to1959 Harley Hummer small lightweights was a 2 brush system and a 4 brush system. The 2 brush was replace with the 4 brush due to the lake of charging rate which could not keep up with the lighting system.
Replaced with the 4 brush could pull off the charging rate needed to supply the needs of the small motorcycle.
