the blue vs the yellow

 No pictures today, but I spent a few minutes attempting to start the car today with no success. You may notice in the previous post that the picture of the new ignition relay shows the yellow wire connected to the positive terminal of the coil. This turns out to be wrong, and it's actually the blue wire that was supposed to be connected, as yellow is normally closed (NC) on that relay and blue is normally open (NO). Fortunately I had the battery disconnected so the coil didn't bathe itself in a warm glow of fire during the overnight chill. I swapped yellow for blue, and the engine started right up. It sounds considerably better with the exhaust leaks fixed (or at least greatly reduced), and the voltmeter now shows a perfectly normal 13.5V with the headlights on. I expect the ignition switch is really happy not to have all that load through it as well. 

While the car warmed up I took the time to fix the burnt-out starboard-side license plate lamp as well. I didn't drive it, but the clutch feels a whole lot better too - it used to be somewhat graunchy which I imagine was the threaded end of the cable scraping over the edge of the throwout lever.
