I think you may have a bad volt meter. You have replaced and checked so many things, there isn't much left. I had another vehicle that I bought for a really cheap price because the volt meter stayed almost pegged all the time, although the measured voltage was within specs. I repaced the volt meter with a new one and it read correctly.
