is my stator heading south?

I notice on my Kuryakyn LED voltmeter that I am running at 12.6 volts at about 3,000 rpm's (one green light) and 12.4 at idle (2nd yellow light). Last year at 3,000 rpm's 12.8 and idle 12.4. So are these symptoms a sign of a slippery slope to replace the stator & R/R and if so what is the cost of OEM parts for the do it your selfer. How can I test it make sure this is the real problem. FYI 2000 vn750 with 15,5000 miles on it.

Note: Those readings were with a voltmeter directly connected to the battery.
thanks, J

What's your reading at 4000 rpm? 5000? 12.6v is a "normal" (cold) reading, tho' maybe a smidge low. Butfor testing the stator/rr situation, you want to see what your battery's reading up in the higher rpms. Should be between 13.5-14.5v (extra voltage helps run the bike, and gets "regulated" back to DC so it can get stored in the battery).

Borrow a real volt meter and test. I wouldnt trust a LED meter

I did use a real voltmeter connected to the battery via my trickle charger pigtail. I would also note that the electric fan was running when i took those readings.

Any load like that (fan) will reduce your readings, so the slight drop makes sense. But do check your voltage at the higher rpms - sounds to me like the battery is properly charged, which would suggest that your voltage in the "recharge" range is more than adequate.

I second that.
The fan takes quite a draw on the system.

How old is the battery?

You can also check the 3 yellow wires that come from the stator that they are connected good. Behind the left panel they connect (male/female) into the bike wiring. Recently I was having major electrical problems and this was one of the problems. Bike runs better and charging faster since I refastened the the 3wires and made sure they snapped in nice and tight.

Mike my 3 yellow leads are fused and soldered to the R/R plug.

Cindy at between 4,000 & 5,000 rpm's I am reading 13.92 volts with the fan not running. I am going to go through the electroux algorythm just to make sure I didn't miss something.


After an hour ride the battery reads 12.96 volts with the bike off and after an hour on the trickle charger it reads 13.31 volts.

Sounds to me like you're in pretty good shape! Always good to do a double-check, though - nothing worse than getting stranded because the r/r or stator decided its time was up.
