So I got the new master cylinder in, bled the brakes down, and now it will not turn over. I'm guessing it is some kind of safety switch issue. Would it be air in the clutch slave? Stumped.

Edit:I notice that the fuel gauge is also registering empty, which I know the car isn't.
Edit, interior fan is only working intermittently. And the radio will not turn on. Maybe a fuse? Don't know why the fan would switch itself on and off. Called the local german auto specialists shop, they were stumped too.
There is actually a bunch of stuff that is not working now. Power windows, door locks, sunroof. IDK. Can't find any bad fuses, but my guess now is somthing "popped" when I hooked the battery back up.

 

I think actually the battery had just run low.
Edit: yup, that's what it was.
Looks nice when it's not up on blocks.
