Loretta,
Sounds like a simple problem with the trailer lights.  Could be a bulb
shorted, a socket smashed, or a wire pinched.  My similar wiring had no
problems on my vanagons.  A meter or a test light should be all you need to
find out.

  Subject: Vanagon trailer wiring help needed

  Hi List,

  I purchased a "hitch haul" wheel-less trailer for my Syncro trip to
Alaska.
  Since the Van's low tail lights would be covered by my gear I decided to
  mount trailer lights to the thing.

  I spliced into the wires for the left and right turn signals & brake
lights
  with no problem, they worked to operate the "trailer" lights just fine.

  The problem came when I spliced into the running light wire (I used the
right
  side) when I hooked up the trailer lights and turned on the lights at the
  dash, the fuse blew for the right side marker (running) lights.

  Is there anyone who can offer some advice on what I can do to make the
  running lights work?  Any suggestions would be appreciated!

  Thank You,
  Loretta
