Re: 3-Star Delusion - "everything works" edition
It turned out that there was just enough speedo cable length to reach the other side of the front hub. I did minorly rebend the sheet metal housing for the drive gear to allow me to angle it farther upwards, I think that made the difference. So now the speedometer works. It's a bit noisy; I took it back off and sprayed some graphite lube inside and it quieted it some. So that part's done.
So, moving on to the lighting, I installed an E10-base 1-watt, 6V LED in the tail light assembly when I put it together. The positive wire was already in place coming out under the fender, but the lamp was designed to ground through the handle back to the lantern battery box. So, by default, my light was grounded to the tail fin since it was through bolted to it. So, I ran ground wire from the lower front corner of the fin into the tank, along with an extension soldered onto the positive wire. I didn't take a picture of the wire routing. However, once I have the wiring attached to the fin/fender assembly, I was able to bench test it by lighting it off of a 9V battery that I pirated out of my smoke detector (note to self - put the battery back).
Next, the headlight needed some modification to make it work. I had to replace the ancient cloth-shrouded wiring, which definitely looked vintage, but was unreliable. I soldered on a new positive wire, and attached a new ground to the terminal contact. The contacts themselves had to be rebent and slightly trimmed to contact the bulb in the correct places (see previous post regarding 1-pin vs 2-pin). This turned out to be simpler than I thought, but I had to be careful to assemble it so that there was no internal contact that would cause a short circuit - there's no insulation on the contacts anywhere. Again, once done, I bench tested the lamp using the 9V:
With the lights wired up, I reinstalled them on the bike and ran the wires into the tank. I mounted a 4-AA battery holder to the side and the on/off switch in the horn button hole (that's why I have a brass bell now). The leads were soldered together and connected to the switch.
And with that, the lights were tested off the AA pack for the first time:
Everything was then buttoned up and taken outside for photos. The timing worked well, as it was just dusk.
OF course, once I took a few pics, I had to ride it around the block...
