Paul,

        With all due respect, I do not believe it is possible for an 
internal battery short of any kind to damage any external cable in 
any way or in any place.  A short simply causes the cell in which it 
occurs to become a useless conductor of current and prevents it from 
producing any useful power.  The cell just goes dead.

        Aa far as the main earth cable is concerned, I do not think 
the fried cable (wire?) Barrie originally mentioned has yet been 
positively identified as to its function or size.  Nor has anybody 
verified that the battery plates were actually collapsed.

        We are all just grasping at straws here.  Fun though!!

Regards,
Dave K.
