Hi!

I have similar problems with the wiring, so I'm borrowing this topic.

I'm changing my TT600S, -95, engine to 3tb with e-start and TCI. I bought a used TCI box and new coil and I'm now doing the wiring and don't get no spark. Should there be 12v in incoming coil wire from TCI to coil(originally orange wire), when i have power in TCI-box?

There's also a gray wire that comes to TCI, is it needed? market in xt600e wiring that it goes to "auxiliary light"?

(edit)Hmmm, now I got one spark when the motor starts to rotate (12v in coil in, I know one is better than none, but still....any ideas?
