 From the docs for csv.writer():
writer(  	csvfile[, dialect='excel'[, fmtparam]])
     ...If csvfile is a file object, it must be opened with the 'b' flag on platforms where that 
makes a difference.

Windows is a "platform where that makes a difference." So try
   self.writer = csv.writer(file("Test.csv", "wb"))
