I've been following the "Burnt Stator" thread with interest. In the spirit of "knowledge is power", I installed a dash-mount voltmeter a few months ago, so I'd have forewarning of problems. I've also considered buying a replacement alternator and taking it with me on long trips.
Well, on this morning's ride, my dash mount voltmeter was reading lower than usual. At times it was showing a steady 11.8 volts. If I turned off my electric vest and grips, it would go up to 13.0 or a little more. (I didn't want to turn off my heated clothing!) Normally, in the past, it would show 14-14.6 volts.
When I got home, I attached a voltmeter directly to the battery and compared to the dash-mount voltmeter. The direct connect was about .1 volt higher, as would be expected.
When I started and revved the motor, the voltage would slowly go up, maybe about .1 volts every 5 seconds. I couldn't keep that up for long for concern for the motor. I expected that it should go up to around 14 volts immediately, which it didn't.
I read the manual and tested the alternator. It said it should read 42+ volts at 4000 rpm. I got 51 volts. The manual says "If the output voltage shows a much higher than the value in the table, the regulator/rectifier is damaged." Is 51 "much higher" than "more than 42"?????
The alternator passed the resistance tests across the leads.
The manual then says to "measure the resistance between each of the black leads and chassis ground". There are no BLACK leads to the alternator; all are white. I assumed this is a misprint, and tested the white leads to ground. One showed no continuity, one had some continuity and one had a dead short.
So, I guess I need a new stator, and it seems like it might be prudent to also install the "Invader-recommended" R/R while I'm throwing money at it.
Best price I found for an stator ($134.99):
Comments/Suggestions? (By the way, my 2008 Versys is just short of 30K miles.)
