14.65 too high at idle, I think it's the rectifier forsure now. Check the battery and see if it's boiling over, when mine was doing it the battery boiled all of the water out of it(twice),I replaced the battery and it did it again, But like I said 14.65 is too high of a reading at idle.

 

I'm pretty sure there isn't... BUT....... Is there any way to test the rectifier?

 

I don't know the anwser bud, I think you're going to have to take it to a dealer's service department and get them to help you. sorry
