Jim--

The heat is not coming as a result of current draw but rather from
resistance as a result of corrosion. Therefore no blown fuse.

Fuses blow when excessive current--above the fuse's rating--is drawn by 
one or more loads on its circuit; i.e. a short (slow-blow fuses allow a 
momentary high draw before blowing, like a Healey's O/D circuit). If a 
fuse has excessive resistance, it limits the current somewhat (like one 
of its loads). Effectively, it becomes a resistor. Fuses don't--or 
shouldn't--offer much resistance, excessive resistance usually comes 
from its connector or housing.
