Hi Johan, 

actually quite obvious. Code works now, many thanks. :-)

import Data.Packed.Vector

data PowerSig = PowerSig Int Double (Vector Double) -- signal Index timeStep

instance Show PowerSig where  
  show (PowerSig idx dt vector) = "PowerSignal Nr: " ++ show idx ++ "  dt: "
++ show dt ++ " val:" ++ show vector    
main = do 

        let p = PowerSig 5 0.1 (fromList [0..10::Double])
        putStrLn (show p)
