I recently purchased a 1989 Goldwing 1500. The alternator had went out on my buddy shortly after he bought it. He had it rebuilt. It lasted about 300-400 miles and went out again. He had it rebuilt again and put it back on. I knew the history and was worried about it - but bought it from him anyway. Once again - about 300-400 miles later it went out again. I noticed a slight amount of oil coming out of the air vent slots on bottom of alternator. Looking thru the forum, I learned there is a rubber o-ring, seal or something that should be replaced when replacing the alternator. I am wondering if this was not done, if there is a slight amount of oil getting inside the alternator and eventually burning it up. Does this sound reasonable (before I have it rebuilt again?) Thanks for any advice.
