Are alternators and diodes something that would typically be repaired?
It all depends on how it's wired. If your alternator output goes through the C post of your 1-2-B switch, perhaps, but sometimes if the batteries have been full and the regulator was not being "requested" to maximize alternator output, the alternator diodes might survive. Only YOU can tell, by firing up the engine and measuring alternator output voltage.

You might want to consider these articles:

This is another very good basic primer for boat system wiring: The 1-2-B Switch by Maine Sail (brings together a lot of what this subject is all about)
