Yesterday when I was driving home from New Hampshire, I went down a long steep grade for about 5 minutes in “B” after about 3 minutes a noise started, a buzzing or humming sound from the engine compartment. There were no warning lights and the only thing I notice was that the battery was fully charged, is this normal when the battery is fully charged? And where does the excess energy get dissipated?
