I had a problem with my G pin connector melting and it was the Ducati brand , it was the only thing installed prior to me purchasing the plane. in the log the regulator was replaced.
because I had voltage issues that was the first place I traced it and looked for a problem.
sure enough it's hard to see pushing that plastic clip up in place upside down on the back of the firewall,, so it bent one of the female tabs Creating a loose fit, and it was a bad connection arcing. A replacement went in and so far so good. I have pictures but can't upload them. I was a bit surprised at the size of those to yellow wires?
