Guys, thanks for all the information. I did notice the 3 metal tabs, but
they seemed fairly solid, and somehow I do not think that I would be
able to bend them back the same way. Right now the switch is 1/2
submerged in a molasses/water bath for rust removal. It has been 24
hours. 80% of the rust came off the keys, 10% of the switch body, 70%
off the copper sleeves from the idiot lights. It seems that this rust
removal method works better for some metals than others. I'll let the
parts soak for another 48 hours.
I went to Wal-Mart, but the only push-on connectors they had were too
large (3m brand). I will try a shop that deals with Italian bikes to see
what I can find. If someone else knows of a source, please let me know.
thanks
Hans

Hi Hans, The Marelli ignition switch can indeed be taken apart and reassembled successfully. Did mine last weekend and it worked fine on the trip to the WNY Rally and back. There are three metal tabs that are bent over the plastic back to hold it on. Use a small screwdriver to carefully bend the tabs up so the back will come off. Probably a good idea at this point to draw a diagram or take a pic of the inards before you move/remove anything. I cleaned the inside with my Dremel then washed out the residue with contact cleaner. Also polished the contacts with the Dremel then used a little dab of "Copper Shield" to protect them. Reinstall the back, bend the tabs back down and test to see if it functions properly. The bayonet connectors can be obtained as Greg said at any number of places - there are different sizes of them though. You'll want ones for 12-16ga. wire (I think that's how they're labeled), if they're the insulated crimp-on type they'll have blue plastic covers. The tip also comes in two diameters (something like .157"? and .143"?), I think you'll need the smaller of the two. They're cheap enough you could just buy some of each. Hope this helps, Hans Rosenstein wrote:
