I have a '46 and I believe my head light wiring goes from my switch to the high beam switch on the floor and then to the head lights. Maybe step on the button to see if either high/low work? After testing the grounds, maybe you can move the head light wire on the switch to the tail light lug and see if you get head lights? Maybe you don't even need to move the wire, just test the lug with a multi-meter when you pull it on. I think that can tell you if the switch is working? Disclosure: I'm not a wiring expert by a long shot.

I actually have to wiggle my switch a little to get the head lights on, so I might be replacing my switch soon.
