Using an encapsulated bridge seems like a great plan, and can easily be
found at almost any electrical supplier. 

They have Fast-on connectors, for easy integration with the Ducati (finally
got the spelling right). These parts also seem to have the right qualities: 

GBPC35 series Bridge Rectifier from Fairchild or the GBPC35A from Vishay (be
sure not to get the 'w' version, which has wires instead of fast-ons). One
could go with higher amperage, but the price seems to exponentially increase
if going much higher, and these are only about $3.00 for the first and a few
more for the second. Besides, only 2 of the 4 diodes are to be used. If it
ever fails, the other two diodes can be accessed. It's like having a spare
part being carried around at all times, so according to Remi, I guess that
means the first two will never fail.  ...Its a Murphy work-around :)#) 

Of course, it would still be good to have a few more reports from people
that have breathed life back into their regulators, just to prove that the
diodes are a common failure. That could be done with a completely burned out
regulator, two 10-cent silicon diodes from Radio Shxxx(Spares?) and a small
load, such as a light bulb...

The problem with external diodes as mentioned above is that the heat sink
they mount to will be at battery voltage.  A better solution is to use a
bridge rectifier so the diodes are insulated from the mounting package.
Then the heat sink will be electrically independent.  Such a bridge is a
Vishay 36MB120A ($8).  This is a 35 amp, 1200 volt device which is similar
to the original Ducatti diodes.  I plan to install this Spring.
