Each week, I make slow progress towards the day my 72B will run again. Last 
weekend, the car finally had brakes and clutch again, for the first time in 
several years, as brake fluid once again flowed in its lines.

This weekend, I decided to let the electrons flow as I finished most of the 
wiring and then connected the battery circuit. With a new wiring harness, I 
wasn't sure what to expect. But when I made the final connection of the 
battery to ground, the first thing I noticed was the red brake warning 
light. The emergency brake was not on. I was not quite ready to turn the 
ignition key yet (no gas in the tank for one thing) but I tested the items 
that should work without the ignition key. So far, only one parking lamp 
worked, no headlights, and the flasher only worked on one lamp. At least 
there were no sparks or smoke.

So back to the brake light - I recall there was some specific way was 
needed to bleed the brakes so the brake switch was centered in the lines. 
Does anyone know the trick to do this? Meanwhile, I'll be checking all my 
other electrical connections as the day progresses.
