Have you checked none of the wires are shorting anywhere first?

Always check teh cheap/free things first ;)

As above check for shorts as the relay sounds like it's working just fine... and so are the fuses ;)

Have a look for melted wires in the relay box, the diode tends to burn out.

Does anyone know the rating of the Diode... so I can order another from the likes of RS? I've just measured one off another Williams on a multimeter and it says '656' but I've know idea what units these things are measured in... Ohms? I'm guessing the Renault OEM part costs a small fortune.
