Update on the effectiveness of the relocation of the Ducatti Regulator.
My relocated regulator has now 150 hours and going. The previous one failed at 100 hours on Hobbs.

The components I used, an Al angle 2X2 1/8" thick with one side cut to 1"wide and a counterplate also 1" wide:
Cuts in the fiberglass of the tunnel:
Regulator secured on the angle:
Regulator installed inside the lower cowl's tunnel:
Lower Cowl in place with Regulator connected including a ground cable:
The ground cable goes to the battery housing:
As I decided to leave the initial connector untouched, I connected the extension I made to reach the tunnel with spade connectors but I had to secure the spade connectors with tie-wraps or risk a damaging disconnection of the alternator. On the picture you can see the stand-by Regulator located at the initial location on the firewall. In case of failure of the active located in the tunnel this standby unit can be switched into active by disconnecting the failed unit and reconnecting the standby.
