The rotor would effect all legs, and since it's a permanent rare earth magnet, unless the magnet is broken/missing, it's probably going to be ok.

- September 19, 2015, 14:27:35 PMWith a good battery I was getting 12.7 volts above idle, high rpm above idle. Ran new ground to chassis from neg ground on the back of transmission. Tested AC out put at the three yellow wires while it was disconnected (troll suggested that in the beginning) and behold a reading I can definitely call bad. Max at high idle was 125vac. That's half what the book calls for. So my alternator is bad. Should I replace the stator or the rotor or both?

- September 19, 2015, 13:35:37 PMI just saw the idea about the ground and I will check that now! I hope that is it! I just put in the new battery it was 12.5 after autozone charged it. I don't have a tach but the voltage only went up .1 volt. I hope it's the ground!

to make sure it is tight and clean.aralph

- September 13, 2015, 19:52:13 PMThanks guys. I have the battery on order and I will let you know the voltage test with a good battery when it gets in!

That's what I have. Same size as the 16 but more power.

- September 11, 2015, 22:38:03 PM"Did you measure the a/c output with the engine running? What is the D/C voltage at the battery with the engine running? Should be 14.5 or so at idle. Mine goes to 15.2 @2000 rpm. see the instructions on page 15-29 about D/C and A/C output." -Troll. I did this with a dead battery. I jumped the bike to get it running and then after I took the bike for a spin around the block I pulled the seat off while it was running and tested it! Not good! I came up with 11.5-12 volts. Then I tried to restart it after I shut it down and nothing, just clicking. So I'm looking at new batteries on Amazon and should have one by Tuesday! If a battery is all that I need... well I'm glad I bought a Kawasaki! --Stein

Can't trust voltage readings when the battery is dead/bad. I've seen it a lot on cars- and assume the same is the same on bikes. The dead battery can be possibly taking all the current and your readings could be incorrect. Might want to install a good battery (you need one anyway, right) and retest....All of these read out good. So my stator and rectifier are good?? I still don't understand why my voltage while running is so low. The battery was shot when I did the voltage test. Would that suck up all my alternator voltage so I would be unable to read correct voltage?
