Hi Remi,
Thank you for a vanilla way of dealing with the problem.

is bolted to a composite structure which cannot act as a heat sink. So it
is necessary to duct cold outside air to the unit fins. I use SCAT ducting to
take the air from the front of the cowling to a plenum riveted to the Ducati
fins.

sandwich structure, there is no way you can compress the ring terminal enough
to make a good ground connection. Now my ground wire is bolted to one of
the regulator fins using a separate bolt which can be torqued properly. See

while the bus voltage was just right. I have since disconnected the L terminal
and installed a separate low/high voltage monitor (B&C).

close to 1000 hours. May be because I have been carrying a spare unit since the
original one failed?
