I remember reading on some BMW site, about crimping solder-less terminals onto the 'pigtail' wire leads on the brushes .
I have to admit, only having done it once 12 years ago, I don't know where the terminal ends go after that .
Are the wires from the regulator go onto the brush holder with nuts and washers, or are they push on type terminal ends ??
Again my memory is vague about this, I haven't had the front cover off of the bike for some time now .
