One of the first things I did when I got my Curvy this year was to pull apart every electrical connector and clean with Isopropanol Switch cleaner(Maplins or Servisol) and once it's evaporated treat the connector pins/sockets with ACF50 and also where the cables go into the plugs.
I also did all my bulb holders including the ones in the Headlight nacelle.
I also spray some from time-to-time down the ignition barrel and the Rear seat lock.
I've been doing this for years on motorcycles and have never had an electrical breakdown since using ACF50 that was not my own fault.
Do this every couple or three years and you can prevent roadside breakdowns over 90% of which are electrical and not mechanical breakdowns.
I also use to to preserve the coolant hoses and my rubber coated brake lines and used it on the Steel braided ones on my other Motorcycles.
I also use it on a rag to wipe the whole bike and then dry off with a clean rag.Obviously keep it away from brake pads and disks.It seems to stop fading on the paint as well
