I am having problems replacing my Fiat Punto Mk1 wiper motor?

I'm hoping someone can shed some light on my problem.

I have a Fiat Punto MK1 (pre-1999), the motor burnt out and so I ordered a Magneti Marelli motor, which is supposed to work with Fiat Punto MK1's.

My uncle and I fit it this weekend, making sure we put it in exactly the same as the burnt out motor we took out. But the result was that the motor moved the wipers down, before it moved them up. Basically, it was not possible to have the wipers in the normal 'parked' position, since it tried to wipe the bonnet, before moving up to wipe the windscreen!

Does anyone know, do the new Magneti Marelli motors need to be fit the other way around i.e. 180 degress the other way. To be honest, I am not convinced it will fit the casing, if we fit it the other way around. But I cannot think of another explanation.
