Stator WTF??
Replaced my stator last Oct, and coming home from work today my batt and engine light came on. Volts were reading between 10 and 11 on my dash. Got home and checked the output to from the stator...2 volts thats it.
Has anyone else replaced a stator and had to replace again so soon? It just doesnt seen normal.
BTW bike is a 2005 Ultra with 79,000 mi. Had 62,000 mi last Oct when the stator was changed the first time.

I had a 2001 EGC and I put 3 stators in it, nobody could figure out why it kept blowing stators so I traded it in on a 2010 EGC. Love the new bike, have 30,000 on it now and im leaving for Strugis in the morning.

some common causes:
1.) dead battery or a short circuit between the stator and regulator or the regulator and battery.
In either case this can cause the charging system to be overloaded.=- if your battery is dead don't try to use the charging system to recharge it after getting a jump start...(unless you are stranded with no choice)
2.) using air impact tools on the compensator sprocket bolt
this can cause the magnets on the rotor to come loose and smack the stator. the magnets are held in place by an adhesive.
3.) heat. high motor/primary heat can damage the stator

Was it an OEM stator? If your bike is stock (you only have a minimum reserve for electric socks and stuff) Something is putting a load on it. If it was OEM, I would replace the battery and regulator. I would follow all the wires to be sure there is no rubbed grounds, insure all real grounds are good. You have a 3 lead 32 volt stator. it's not a lot of amps but it makes a good system. I would also check the breaker in the line mainly the wires in and out of it. My Softail is up under back fender and gets some splash. I bet you have a high resistance. I assumed you unpluged stator and checked the three wires. Are 2 dead? Remember it's AC--not DC and should be 32-40volts across each lead AT 2000 RPM. How do you know battery is good? The regulator can go on a car and actually put AC to the system and take out the electronic ignitions in older GM cars. Think Harley will not do that. Know the ECM is protected against reversing the battery cables

Battery is less than a year old (changed it last year when my stator went out the first time) I pulled the batt tonight and it has about 12.8 volts. When I put it back in and started the bike it dropped to about 10.8 to 11 volts.
Both stators that have gone bad are OEM parts. I have the 95in big bore kit and gear drive cams stage 1 and sert. All those mods were done 4 years ago. I don't have any idea what could be causing an extra load on the system.
This bike has always been reliable, except for the last 10 months two stators and a fuel pressure regulator.
