My pin burnt away as well. I also drilled a small hole through the plastic top and connected the wire with a bolt, nut & spade connector. I had a small leak where the burnt off pin
was, which I sealed with epoxy. Seems to be holding out so far.
Elmer, depending where you live, you can give Shaun Stick It a call. He is in Hillcrest. Phone 073 2159367. Apparently he is very good. I want to get him to make a few stickers for my Husky 701 fairing shortly.
