It sounds to me like the sense lead to the regulator is  intermittent.  The 
fault may be internal to the regulator, or it  may be a loose or broken 
wire.  I think on the Vans alternator hookup that  one of the wires going into

the back of the alternator would be that lead.   It may connect directly to 
the field supply near the connector going into the  alternator.  At any 
rate, carefully check that wiring by tugging on the  wire while you have a 
voltmeter connected and the alternator and master switches  on, but disconnected

from the alternator.

If no problem is found with the wiring, replace the regulator (inside the  
alternator), or replace the alternator and regulator -- regardless of what a 
 bench test shows.  There isn't as much vibration on the bench as there is  
on the Lycoming!

If the sense lead opens up the alternator may go "full field", or it may  
not -- depending on whether there is a fail safe internal circuit to pick up  
another sense point.  (GM regulators have this safety feature.  Not  sure 
about Nippondenso.)
