Alternator question

[KenC210 3]

So I sent in my alternator for repair and the message he sent me was,

The rectifier was overheated and the rotor was open (this alternator design is very compact)

I have everything broken down for a full rebuild other then the stator now. The stator is in perfect shape still and was never overworked. 

Just waiting on the parts to install them. 

So I don't know much on the process it takes to rebuild my alternator sui could someone she some light on this message he sent me.

Why? Do you not trust who is doing the work?

I trust who is doing it im just curious what it is I know nothing about the alternator.

I really don't like to tamper with things like that, haha.

I'm more curious about what he says about the rotor being open and what that means.
