One stator fried and shorted to ground at 13K, and one just died at 17K and went open when the lead that connects to the winding melted or vibrated off yesterday . I used a OE HD stator last time and will see if its covered by warrantee (3 months 8 days old- good luck! If its not covered may go with Excel due to life warrantee, anybody Know if they last along time and good quality?
A day later my local HD dealer looked at the stator and agreed that it was faulty and gave me a new one. I cut one of the two stator wires near the connector, and installed a 25 amp blade type inline waterproof fuse holder and fuse. I measured 26 amps at 4K so I tried a 25 amp fuse, hope it blows a fuse and not a stator next time.

My first stator failed at 24,000 miles, and the second one at 50,000. Still running the original regulator.

Edit: Does anyone know of a manufacturer that makes a "Series Regulator" for 04up Sporties? I've found several for 03 and earlier, but nothing newer. I'm thinking that getting rid of the stock "Shunt" type reg. may help the burnt stator issues.

If you mean the normal automotive type of regulator, it won't work as the magnetic field is permanent magnets and not electromagnets.

No, Series regulators vs the Shunt type regulators used by HD. They are made specifically for HD applications and are available from several sources. Unfortunately, the only ones I've found for the Sporty so far, fit the 2003 and earlier models only.

Do the rectify AC to DC then use PWM (pulse-width-modulation) to keep a certain voltage output?

Harley-Davidson "shunt" type rectifying regulators dump current to ground. This causes maximum stator current and temperature at all times.

Series rectifying regulators block current to control voltage. This reduces stator current resulting in lower stator coil temperatures and less drag on the motor.

You can find Series regulators listed in most of the common catalogs, like Drag Specialties, etc. Just not for 04 and up Sporties.

OK, here's a dumb question - What syptoms would one experience if you had a bad stator?

I've got some weird electrical shit going on with my electrical system and I'm hoping it's just a bad battery. I'm going to have it load tested tomorrow.

Replaced stator, regulator and battery just before the run to Deals Gap. The stator had burn marks on it and the battery was original stock with almost 70,000 miles on it. Still had some electrical concerns and when I lost my driving lights , on the way up north, I found the light relay warm to the touch. Pulled it out and noticed a small trail of rust down the top seam on one side. Opened her up and found RUST everywhere! Have just gone through her and did what I should have been doing on a regular basis, cleaned all my connectors , added dielectric grease, sealed all relays, and cleaned and sealed my battery cable ends. (Do have new cables on order, and suspect a starter solenoid issue remaining) Always seems to be something, ain't it fun?

Run a diagnostic test.

My stator said hi to the rotor and I had graphite chunks in my oil... thats one way to discover a bad stator. another is crack open your inspection cover. burnt stator oil stinks like rotten crotch... another way is to get a manual and do a diagnostic test on your charging system.
Electrical problems are a pain in the ass...

Update to my Aug. post (#13) above. Stator #3 just took a dump after only 13,000 miles.
#1 @ 24,000 miles
#2 @ 50,000 miles
#3 @ 63,000 miles - on the day I'm scheduled to leave on a 2500 mile trip.
(no regulator failures)

There has got to be something better than these pieces of trash the MoCo is producing.
