My first suspect was the multi-pin connector going to the Ducati voltage regulator - at least twice before that's been the culprit, once with corrosion due to water incursion and once due to the minor burning mentioned below.
I had a heck of a time getting the plug out. When I did, this is what I found:

I had seen minor burning before on one of those pins, but nothing like this. You can even see a little blob of solder in the photo above, and the male connector was ever-so-slightly deformed in that area, which is what made it hard to pull out.
A fellow at the airport thought a loose spade connector in the multi-pin plug could be the culprit, with the bad connection leading to the high resistance and resultant heat.
Long story short, I cleaned everything up as best I could with a wire brush, applied some Stabilant-22, reinstalled and the problem is fixed, at least for now.
I happen to have a spare plug, and I think replacing mine would be wise. I would have done it yesterday, but did not have the right crimping tool at hand.
Any thoughts? Anything to look out for when crimping the new spade connectors?
Thanks in advance.
