Ahoy the forum. Bit of a peculiar one. I've been having headlight bulbs blow every so often, which I put down to vibration until I put an LED bulb in and had that fail too after a couple of months. That finally prompted me to check the voltage at the connector, and I saw 15.2V across the open circuit.
Not crazy high, but higher than I'd like, and at this point I assumed that the battery was seeing that voltage too. So I ordered up a £30 Chinesium reg/rec and have just thrown that in.
Now I'm seeing 15.0V at the headlight connector (open circuit). The plot thickens when I checked across the battery terminals and got a more reasonable 14.6V.
I've checked back and forth a few times and the voltage is consistently higher at the headlight than the battery, and both stay pretty much constant with revs. I don't see any sharp spikes or dips when revving, just the usual 0.1V or so brief wobbles before it settles down.
There's no aftermarket wiring or any modifications or electrical repairs or bodges to the bike (2011 F650GS twin).
I assume that this is some sort of evil canbus sorcery, but was wondering if anyone else has seen anything like it.
At this point I'm minded to just feed it a regular diet of cheap bulbs rather than spend time or money investigating further, as long as it's not cooking the battery.
