OK, sorry for the delay. I pulled off the engine spacer (came out much easier this time) and did two things.
1) I checked the circuit for the light. Multimeter thinks it's a good circuit. It reads open anyway. Now, I really suck when it comes to electrics so nothing is too simple or obvious.
2) Then I checked the switch itself, which is still in the transmission. No circuit. The old switch, which was leaking and working intermittently does show an open circuit. Question: is this switch bad? (it's in the bike, in neutral, no transmission fluid yet). I would assume, remember I don't know much, it should read open circuit (as in: multimeter showing some reading - like when you touch the two leads).
Big reason I pulled it all apart again, other than it doesn't work, is that the excellent article by Snowbum states that you need that spacer, which I stupidly didn't see on the old switch and didn't come with the new one. I will install with the old one.
"if you forget to install this ~2mm washer the neutral lamp will NOT work correctly, no matter which switch you have installed....and you may have shifting problems."
What do ya think?
