historical comparison and nothing more.
as a side note, vehicles today have the capability to completely shut off the charge system for what ever reasons like less drag and etc.
not related to hd but in a way does show a weak point in their system for $$$$$ reasons, parasitic drag.

Buster, one of the Japanese bikes I owned many years ago was configured with a rotating electromagnet, which spun inside of the stator. The rotating electromagnet assembly used brushes to allow current to be sent to the electromagnet.
This would allow the voltage regulator to actually control the output of the alternator, correct?

which machine? honda used a rotating magnetic core but no brush setup. basically the same as the hd. pass the magnet or pass the wire, tit for tat. suzuki used a lighting coil and a selenium rectifier system on some but no brushes. the old shovels had a field forcing winding in conjunction with the main winding which worked well but the weak link was the special regulator, still no brushes. i can picture the brushes but cannot conjure up the machine. yamaha and honda were similar in many ways but i only fooled with the two cycle side. my fastest ride was the 305 two banger yahama at 135mph. a friend of mine had a tricked out twinjet 100 that clocked right at 120mph but he weighed less that a fart. gone are those days and a lonely 3 mile stretch of country road, shoot, even some of the popo came out, back when they were your friends, until society changed that!

i just remembered my brother-in-law's yahama 650. his father pushed out under the roof's edge and since he worked long term away from home, the engine seized up. if i am not mistaken, it used an electro-magnet, aka, there were no permanent magnets. the regulator feed power via the brush assy to the core and the core varied the field to raise/lower output just like a car alternator. i had to pull it apart, how moisture got into the cylinders is still a mystery but the pistons seized to the cyl walls.
