I have a voltmeter now and I see little, if any difference in the reading at speed when switching the headlight on and off, but at idle there's quite a drop when I turn it on, a good half volt or so. What I don't like about the auto-on headlight relay is that it doesn't only turn the headlight on once the bike is running. A long, sustained starting attempt is enough to spin the alternator up and trigger the relay. The light comes on even though the bike isn't started and running yet. Then you get that big draw on the battery. The only way to turn the light off is to cycle the ignition switch off then on again.
I'm all for riding with the headlight on at all times, I just want control over it. For years and years, that's the way it was. I guess the government thought we all suddenly got stupid or something, forgot how to operate a simple on-off switch, lol.
