Smoke means you're shorting out... but not necessarily within the switch.
It could be that one of your wires to a light is shorted, at the light, or anywhere along the pathway to the light.
Those old cloth covered wires don't age as well as the rest of the tractor.
The best way to fix that kind any wiring problem is slowly and methodically. it helps enourmously to have a multimeter to test with, but if not, you have to get creative.
Make a note of which wires go where, then remove them all. Test each one, one at a time.
If the switch turns out to be the culprit, it COULD possibly be serviced, but they usually only break down from corrosion, or something cracking apart. You'd save yourself a heck of a lot of trouble just buying a new one.
I believe they're in the $40 price range. Not cheap, but worth every penny compared to fighting with an old one.
But definitely check out all the wiring first. It will get twice as expensive if you throw in a new switch and it burns up too!
