Central locking

[Alasdair Mackintosh <alasdair@sdlunix>]

  Hello all,

  I have a early 1986 model Audi 80 ( Audi 4000 in the US, I believe) whose
  central locking recently died on me. The pump that drives the system is
  still fine - I connected the battery to its terminals, and the locks opened 
  and closed. This suggests, even to inept electricians like me, that there's
  something wrong with the wiring. (It isn't the fuse. Life ain't that simple.)

  Before I start to trace through all the wiring, I was wondering if anyone else 
  has had a similar problem, and could give me some clues as to where I should 
  start looking.

  Thanks,

  Alasdair
