[C320-list] alternator question

As I understand it the diodes blow when an alternator that is generating power  is suddenly disconnected from the load

This implies a port connection or fractured cable between the alternator and the battery

Could you have a cable with an internal break ?

Anyway, the batteries are 1 year old (2-1100cca batteries)  I set up the first new alternator and indeed it appears that the diodes are blown.  That being discovered I am even more perplexed as to what I am doing to blow the diodes.  As I stated before both alternators worked briefly and I did not turn the key off before shutting off the Perkins m30 engine.  I don't know what to check next.
