Low voltage
The other night I was on a ride when I noticed the my voltmeter read 10 volts, usually a little over 12 on the meter at higher rpm's. Went home and charged the battery, then had it load tested at Battery's Plus. Tested good. Put it back on the bike and put my digital multimeter on the battery and started it. Ran up the rpm's to 2000 and the meter stayed at about 12.33 volts. Bad stator???? Less than a year old stator. Would like some opinions before I either take to my Indy or read my service manual and attempt replacing it myself. Ant help would be greatly appreciated.

Definitely could be regulator. You should see at least 14v DC from regulator. Like previous post unplug the stator from the regulator and check with a meter on AC volts. Should see 18-20 vac per 1000 rpm. There it's a good stickie in the electrical forum that walks you through checking your charging system.

Yeah, from what I understand the voltage not running up on higher rpm is a bad stator. I looked on you tube and seems to be not a horrible job to do in the garage.

Check the wiring coming from the voltage regulator. Check the plug at the stator, they are known to corrode. A guy I rode with last weekend had a wire coming from the regulator to the battery break on him. Bike wouldn't charge. Stator and regulator were both good. He thinks it may have gotten pinched when he had it on the jack over winter.

Many thanks for the inputs, guys! Hopefully tonight I will get a chance to do a final diagnosis. If it is the stator, has anyone replaced one on an Ultra? If so, any surprises in store for me, or any tricks to make it easier?
