Due to some of the threads re charging voltages at lower RPM's, I made the below video to clarify.
History on the bike;
(1) BD43, dual headlight mod, PIAA high performance bulbs
(2) Battery is approx 3.5 years old, (ridden 365), and due for replacement.
(3) Idle is intentionally set lower than recommended (so at 1200-1300 RPM your voltages should be slightly higher).
(4) Stebal Air horn installed.
(5) GPS is NOT plugged in while recording.
The video was recorded from a dead cold start and eventually idles down.
(about 85 degrees F in the garage at the time)
The meter was hooked up NOT directly to the battery but thru a Powerlet Outlet on the left side of the bike. Voltages would be higher at the voltage regulator and would also show higher with a newer battery.
Note that the meter takes a couple of seconds for the voltages to change, even with the throttle set steady. Also take note that a decent charging voltage is available just off idle. While 5,000 RPM's is the max charging RPM's, the machine does charge well under 5,000 RPM's..
Towards the end of the video, I activate on the Stebel Air Horn for several seconds. You can see, at least at idle, how much it draws from the system.. (Flickr didn't upload the end of the video, so the Stebel activation is NOT there)
Hope this helps in deciphering charging issues, a visual, on what to expect.
