Repro kill/horn switch

The reproduction kill/horn switch arrived yesterday. I ordered it from Danell at SPD. She told me that it is a quality reproduction piece in comparison to a lot of the not-so-good stuff available.
She also said that the back plate was thick and solid. This plate is split on half on my original, hence why I need this one.
I purchased this for $34 with a 10% discount. Most shops had it listed at $39, but I saw ScooterWorks had it at $25 and when I check again it was $35 or something.

It is my intention to re-use my original chrome cover for the switch if at all possible. Trying to preserve the soul of the bike as much as possible.

This is the first step in getting this bike diagnosed for (1) electrical issues and (2) not running correctly, Paul S. says. Since my original switch back plate is broken in half it is grounding it out.

It is super challenging to find NOS for this piece since all 1960s Vespas used it.

Horn

A while back, before I was scooter shop snob and became a much more picky restorer, I ordered a horn gasket from Scooter Works. I know that Palmog ordered a gasket (from who I don't know) and the rubber was poor quality and actually ate away at his paint. I am going to keep a very close eye on this gasket to be safe.

When I look at the original gasket (pictured left) verses the new gasket (pictured right), I am bummed. They clearly look different. I need NOS for this. The stock one is much more intricate and pleasing to the eye-- not to mention the diameter is larger and fits 100% perfectly in the frame is was designed for. Luckily, this is something that is easy for me to replace later on.

Using a very mild abrasive pad I polished the rust off from behind the screw and made the horn shiny. I used compressed air to clean it out behind the horn grill. I decided not to sand the rust behind the grill too much because (1) I need to get the bike to the painter very soon for touch-up and (2) I didn't want to scratch up the exposed grill by reaching sand paper down there. I did use a tooth brush to clean off the surface rust.
If memory serves me correct, when sitting in front of the horn, I attached the white wire on the left and green on the right (pictured at the very top of this post). And I also covered the terminals in a protective connection grease, which will protect the terminals from the elements and also improve the electrical connection.

I used fine grit emery paper to clean up the pitted tops of the hardware for the horn, but I will replace the hardware to shiny stainless steel after I move back West this summer. I leave in early June. At this point, my take is I won't loose it if it's installed on the bike and if it's easy to replace late . . . then no big deal.
