GOOD NEWS EVERYBODY!
I found where the smoke came from.
You are looking at the underside the light arm in an early combined unit. That copper plate came loose, and that spring was being dragged around the terminal(s) reserved for the copper plate. HOW RUDE!
This is great though at it means this indeed was where the smoke came from. Note the orange burn marks and melted housing directly under the spring.
When I took it apart I was very confused. the copper plate, which should sit like this,
Was found at the complete other end!
Look at him with his arms out reaching for another circuit to short! What a sneaky sod! I'd hate to think how long he was apart like that. There is enough dirt and geese in there that I'd be confident it would start a fire if left... :S
It's a pretty fun little unit actually, but lets back up a bit and I'll show you how to get into it.
First get a dremmel and grind out the rivets. Oh I got a dremmel for Christmas. They are great! I managed to not destroy the housing and I think I'll be able to take it to my friendly bolt store and with a series of spacers install a replacement that will allow to me mount it back correctly!
Then bend the terminals 90 degrees do you can slide the ends out of them. Lastly there are two boring clips on the other end that pooped of easily enough, Didn't bother to show that here.
From here you can gaze upon the boring blinker side, which is really nothing but a case. The circuits on the outside seem to control the indicator, well report it's position to the switch.
Turning the lights on, actually moves a small arm on the lever that pushes on a plate within the housing, When its it's in configuration it looks like this;
The high beam flashing circuit (pushing the arm in) is controlled but the cap expanding into the sprung lever, Shown at the bottom of the image. That bar simply gets pushed into the terminal
The high beam switching circuit.. well I'm not exactly sure. There is a sliding plastic piece that moves between to the left and right position but has no contacts and connects not a thing. I have a feeling there were small springs that provided tension on the leaver and returned it into position. The circuit is control by the plate what failed above on mine. You can also clearly see the wear on the terminals from the copper plate traveling previous.
So I think I'll spray a lot of WD40 in there and clean it out as best I can. Apply a little more grease to the moving components, and think carefully about how the high beam circuit was supposed to be support by some small springs, and just how they connected.
This was the part that failed a pink slip actually. The sloppy lever was not welcomed by the mechanic.
Someone take theirs apart so I can see which bits I'm missing
I'm glad I confirmed this is where the fire came from, I'm feeling a little easier about the wires under the dash now.
