I spoke too soon about everything working o.k.

O.k. with ignition switch in normal running position, but in taillight position, headlight comes on instead of taillight. I think the diagram is right, buy I mis-wired something. It'll be a while before I get it sorted out - I'm recovering from back surgery last Friday.

Seadog, here's a link to a turn signal switch from K & S: http://www.ebay.com/itm/K-S-TECHNOLOGIE ... eR&vxp=mtr
I was right about the price being a lot higher than I paid for the other one. The wires on the one I got were just barely long enough. It looks like if you want to keep the wiring inside the handlebar, the wiring on the K & S unit would require some re-work.

Sorry to hear of your back surgery. I hope you recover quickly. I had some of that myself, about 4 years ago. No fun.

You'll figure out the wiring snafu. Give it a break for now and concentrate on feeling better. And, if you're on pain meds, wait for a clearer head.

Thanks for the link to the switch.

The next time I tried the lights they behaved differently - got no lights at all with ignition switch in the tail light position. I have no idea why the behavior changed.

Anyway, I decided to tackle the only symptom that was showing. I quickly realized that when the ignition switch is in the tail light position, the converter module is not getting any power to its supply line. I fixed this by bypassing the converter completely for the tail light wiring. Works like a charm. Tail lights come on (as they should) when ignition switch is in running position and headlight switch is on.

Update schematic attached.

Wondering if anyone has the Photos from this post. They don't seem to be available at the moment. Thanks!
