    20VAC between phases, times 3 phases = 60VAC. I think you are OK - proof being 14.5 V DC to the battery.

    Its a minimum 60v from each stator wire, I saw 70v at 3500-4000 rpm & it climbs from there if the stator is healthy. If he's getting 14.5v out of the rectifier & only 20v from each stator leg then he measured the stator wires incorrectly.

    60 V AC from each PAIR or wires, but yup and yup.

    do a search on stator and or voltage.. it has what the combination of wires are to get the correct stator reading.. i had the same issue.

    trust! the book says 60V AC between each phase @4K.

    Seems like this is a non issue as he has perfect charging output with Bikpainter's reg. With the stock regulator still in place(stock connectors, 4 wire mod) mine gets about 14.4 @ idle and drops to 14.1@ 4k. I have no battery issues. rick

    Remove the two left side body body panels, drain the oil, disconnect the brown and white connectors and remove the rectifier and it's heat shield.

    Remove two nuts and one bolt holding the oil tank, disconnect the lower rear hose from the oil strainer, disconnect the small upper rear vent hose. Leave the hose to the oil cooller attached and hang the tank by a bungee from the left handlbar end to gain room to remove the stator cover.

    Disconnect the small white electrical connector to the side stand switch, fold the disconnected ends back out of the way. Tape or otherwise hold the wire to the neutral light up out of the way.

    Remove the 13 (give or take one) screws from the stator cover. Tap the cover with a plastic or rubber mallet to break it loose, pull it off the bike and place it upside down on your workbench as the remaining oil drains into a pan from where the cover was just removed.

    Remove one bolt holding the wire loom cover inside the stator cover. Remove the 3 screws holding the rotor, remove the stator from the cover. Send for rewind. Wait patiently. Jump up and down when it arrives.

    Reinstall the rewound stator, making sure the wire leads are properly positioned to be held by the loom cover. Put the loom cover in place loosely. Tighten the 3 bolts using a medium thread locker compound. You did clean the oil out of the holes, right? Tighten the scews sequentially to the correct torque; look in the engine manual or use a standard value.

    Using the new gasket you ordered, reinstall the stator with cover, again torquing to proper value sequentially working around the cover, watching to be sure the gasket is in place and all else is out of the way with a mirror and small flashlight.

    A few pics disassembling the stator from the cover:

    This last picture shows something to be aware of and careful of. Some of the epoxy Rick's used chipped off when the retaining bolts were tightened. The chip was "non-fatal" as the windings were still held away from the iron core. To be safe, I filled the chip with some epoxy I've used in the past with good results. I allowed it to cure at about 80F for two days before completing the reinstall.

    Good write-up!

    And, how's the charging now?

    everywhere you said rotor, you meant to say stator, yes?

    Yes. Thank you. Doh, I have "rotor" on the brain. Sigh.

    Much better. Would you like numbers?

    I was just curious if the whole operation solved the original problem.
