I ride a 2011 Heritage Softail Classic with about 19,000 miles. Lately the charging system works sometimes and not others. I have tested the stator and VR and haven't found a problem. Replaced the battery 2 months ago. Today I had a local mechanic test it, not a dealer. He says oil from the primary case is leaking through the stator wires into the plug and into the VR. I have noticed some oil there when I have pulled the connection apart but thought it might be dielectric grease. He thinks I need to replace both the stator and VR. Has anyone ever run into this before? I would think the cables would be sealed better than than. New one on me.
