about ten minutes later, it's back up to 14.6 and stayed there.

any ideas? time to check the mags?
Although a possible anomaly, when mine started oscillating like that the rotor magnets were migrating. Some days voltage was normal and constant, others were like what you are experiencing. Eventually is was dropping to the mid 12's

I agree that you should check your magnets! Sooner than later. In my opinion, the magnets being out of place are harder on the stator. If you fix that now, you may save the stator.

thanks for the responses. not that i disagree but i find it interesting that suzuki does based on what the service manual says.

Suzuki will not admit the magnets can come loose, even though the changed from glued on magnets to embedded magnets on later models. That's like they did a recall on 2012 and later stators but not 2008-2011 stators of the same part number.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

That manual was written long before they knew they had magnet problems and would make sense for many bikes just not in this case.

Hmmm. I replaced my battery about a month ago (2004 DL650) and added a voltmeter at the same time. Test with multimeter shows that voltmeter reads within 0.1V of battery. Voltmeter wired directly to fuse box.

Riding with no accessories: 14.4V
Riding with heated grips and phone charging: 14.2-14.3V depending on grip setting
Idling at stoplight w/grips & charger: ~12.3V (I'll watch more closely next ride.)

Based on your chart, this indicates a problem?

Your system is only discharging at idle. That may be an indication of something being amiss that may change in the future so keep an eye on it. As long as you are charging at such a robust rate, you'll be okay. That will more than overcome the slight discharge rate at idle. What is your idle speed set at? It should be around 1300rpm.

Idle is 1300-1400rpm. I'll keep an eye on the voltage. Next ride I'll pay close attention to voltage levels and report back.
