 The regulator referred to is not made by Ducatti but by Tympanium, follow
 this link for more info: http://www.tympanium.com/app.html
 As with all permanent magnet alternator shunt regulators you need to ensure
 the heat sink face is attached to a metallic surface.
 Screwing them to a plastic firewall inside a hot engine bay is part of the
 problem.
 Poor AC and DC wiring/connections to and  from the regulator and alternator
 is another.
 Inadvertently disconnecting from the battery whilst the engine is running
is
 another.
