I fired up Barney with the intention of heading out to do some errands; got to the corner up the street and hit the windshield wiper switch to clear some dew off the glass -- nothing happened. So I hit the heater fan switch, and nothing. Ditto the turn signals. One U-turn later, I was back in my driveway trying to figure out the trouble.
What one thing do all these items have in common? They all run off the car's Accessory bus, the electrical circuit that is energized only when the car is running.
I fired the car back up and... everything worked. Shut it off, turned it on again and... no accessories. Wiggled the key and they came on! That put the point on it: tired ignition switch, which will have to be replaced.
Luckily, Stude vendors like Studebaker International and Chuck Collins' Studebakerpartsonline.com have reproduction switches that will slide right in. One more project for the list!
