That is one of the worst mechanic tales I've ever heard. It doesn't even begin to make any logical sense. He is either incompetent or sees you as a mark.

Let's just start with this: if his voltage theory were correct, wouldn't low voltage make it spin SLOWER making it QUIETER? The rest of this "theory" isn't even worth the time to tear apart.

yloDiscoII is pointing you in the right direction to solve this.
