The wiring diagram says the switch is 'Normally Open' which to my mind means when the tractor is running and used, the seat is down (and switch plunger is down) there is no continuity between the Blue and Violet/White wires. In my case I have continuity when the seat is down and no continuity when the seat is up. Am I misunderstanding what is meant by Normally Open, or perhaps I have the wrong switch?

Normally open or normally closed means untouched/ unactivated/at rest,
or,as built by manufacture, not as installed.
As for ignition switches, they are a common problem as the
spades/ connectors
corrode, making no contact or when they do, arc and get hot melting the plug as you have seen.
Do make sure both male/female connectors are clean making good contact.
Better yet, replace them, they are available inexpensively from ebay suppliers if you have not already.
Trust us, they are a problem area.
