Three months ago I dealt with the alternator shaft broken bolt syndrome. When re-installing the alternator, I was very careful not to pinch the O ring. Got to work this morning, oil all over the side stand and underneath. At first I thought it was the countershaft or output shaft seal, but following the oil trail, I tracked it down to the alternator. I'm bummed out that I have to do it again and I just needed to vent.
