All my idiot lights are on - why?

[keldrid@gte.net]

New to Audi's in general, but I've been told that German cars expect you to
pay attention when they tell you something is wrong. Last night, my (new to
me) '84 4ksq was running fine when I stopped at the store. 20 minutes later
I got in and drove home (a half-mile) but the idiot lights never turned off
once the motor started. From left to right, the OXS, the flashing temp, the
battery, and below that, the brake. It all ran fine, temp was cool, battery
was batterying, and the brake was off. (pull on the brake handle, the brake
light gets brighter). Any idea what relay I may have kicked out of place?
Just to be safe, I benched the car today until I can get an answer.

Any ideas?
