split washer in coil

[andy65 <andy65@snet.net>]

There is a small copper washer with a slot in it that goes inside where the
high voltage wire screws onto the coil.  What is the proper way to attach
the wire to the washer?

My high tension distributor wire just has gray hair like fibers in the core
surrounded by cloth insulation and then rubber.  Is the washer just for
copper core ignition wires?
