So…. I bought a 2014 R1200GS a little over a month ago. Lots of power. Handles great. Comfortable ride. Blah blah blah. A couple of weeks ago theres a glowing red triangle along with the battery indication but it resolved itself. The next day I get the same indication but again, it goes away. The charging meter looks like all is well so I’m thinking it’s probably the battery. Maybe the rectifier. At worst, an alternator. No big deal. That was before I read about the LC boxer and it’s fancy shmancy integrated %#@ charging system.

Not cool.

I charged the battery. It checks good. Holds its charge. Voltage drop on engine start is good.
Removed both connectors from rectifier. Pins look good. No corrosion. The gray ac connector pins have oil on them:(
DC output voltage test:
- engine running, hi-beams & grip heat on = fail.
- no load test = fail.
- Rectifier bench test
- No defects.
- AC Output check:
- found short to ground on all three pins of ac output bus connector:(
- removed fuel tank and exposed harness. No defects.
- I checked all 3 wires where they exit the gearbox. All 3 = short to ground:(


😞… So it looks like the stator has failed. I would love it if someone could prove me wrong and give some trouble shooting help. Thanks for reading my post!
 
As much as I would like to tell you, your problem is a simple inexpensive fix it sure sounds like the charging system is tits up. Did you buy the bike from a dealership or private? If it was from a dealership I would talk with then to see if they can work with you on repairs

Cheers,

I burnt up my stator on my 2014 by idling in traffic coming out of Kings Canyon on a 100 degree day. Symptom was charging dropped to sub 11 and battery wouldn't turn over bike. Trailered home and dealer replaced under extended warranty for $3500. Stators going bad is pretty rare.
 
I guess I’m just lucky
Are you? The stator generates current, if you measure good voltage then why do suspect charging system? Could it be a short in one of the aux systems you loaded it with, also you did find some connection issues, did you try after that? I replaced a battery that I assumed was 3yrs old and then when swapping noticed loose and dirty connections. It had given me several odd errors, false neutrals etc but like yours my old battery checked out later and is now collecting dust, I won’t make that mistake again 😉

I checked for continuity with the bike off & the stator disconnected from the regulator. The connector showed all 3 phases shorted. Checked all 3 wires where they exit the gearbox. Same result. So with the battery & everything else out of the equation, it’s reading a short. But I’m all ears if you can tell me why it would still be a good component.
