Oil leak - right front side of crankcase
I have an oil leak on my 2011 FLHP.
It is coming from a three wire connector on the front right side of the crankcase. This connector is below and to the right of the Crankshaft Position Sensor. It is very low on the crankcase and almost to where the crankcase and primary case meet
Although it seems highly unlikely to me, these three wires appear to come out of the crankcase.
One of the three wires go to the Jiffy Stand Sensor.
The other two appear to go to the Voltage Regulator
I tried taking some pictures, but none of them were very good. I hope the verbal description will be sufficient.
I have spent most of today scanning the service manual to no avail.
So, I have some questions:
- Do these wires REALLY come out of the crankcase, or is there a switch that these wires are connected to
- If there is a switch, what is it called
Hope this makes sense.

I think you are talking about the stator wires, the only real way to fix the leak is to replace the stator, but I have seen guys clean it real well with break clean , and then use a toothpick, and poke RTV silicone in there , let it set for a day, and it lasts for several thousand miles.
Oh to clear up confusion, that would be on the left side of the bike.

Sorry for the confusion. I've never known how to tell the left side from the right.
I think Bill03E has got it. I looked up the stator in the service manual and it sounds like that might be the problem.
To clarify (hopefully)
- It's on the front of the engine on the same side as the Jiffy Stand.
- The Crankshaft Position Sensor is also on the same side.
- The leak is coming from a connector or seal that is below and to the right (looking at the bike from the front) of the Crankshaft Position Sensor.
- It is very close to where the primary case attaches to the crankcase.
Thanks

That's the stator wire plug. I had the same leak. Fixed it with Ultra Black RTV. Do a search on stator in the forum for instructions on how to fix. Otherwise you will need to replace the stator.

However, this leads me to, hopefully not too dumb, question 1:
1) Is the leak engine oil or primary oil??
I changed the oil, all 3 holes, about 2000 miles ago. It was my first time. When the dealer had changed the oil in the past, the oil level barely reached over the 'add' line. I added a little bit more oil to reach half way between the 'add' and 'full' lines.
Dumb questions number 2:
2) Did I bring this on myself by overfilling the crankcase??
Thanks

Thanks. Once Bill03E told me what the leak was (in spite of me not knowing my left from right), I did some searching. Using the RTV seems like a good thing to try, as long as I can get things completely clean and dry.

Yep... Sounds like the stator grommet is leaking. Very common. The RTV is a good fix if done properly. I've done both of my bikes this way.
The attached thumbnails show photos of my repairs... Take note of the RTV between the grommet and the engine mounting flange ("A" Motor) and the engine case ("B" motor). I filled that space with RTV to provide some extra stability for the grommet.
And here's a couple links to discussions of this same topic...

And for the left/right thing... Just remember that left and right are as you sit on or in the vehicle.

the stator is covered under warranty..
if you are still under normal or extended, then take it in and they will actually put in a brand new stator for you...
Had same thing on my 09 Road King... 50 bucks for my extended warranty and they replaced it with a brand new unit.. was aroudn 30k miles at the time.
