The brushes must be smooth where they
contact the slip rings. If not, polish smooth the
brushes with sandpaper. A brush that is not
smooth produces arcs between the brush and
slip ring leading to possible damage.
Usable brush lengths are from 7 mm to 11 mm.
A brush shorter than 7 mm must be replaced
because decreased contact pressure between
the brush and slip ring lowers generator
efficiency and output voltage.
