The power steering is probably not working "because" the battery light is not on. The electric steering uses a lot of electricity so if the cars ECU "thinks" the charging system is up the shoot I think the car would start but without electric assistance.

With your car could still be a duff alternator with a faulty charge indicator. When my Punto had a duffish battery it was regularly starting without its power steering.

Has anything else been "fixed" recentley that could have disturbed any earth connections?

Have you had a new alternator recentley? If you google "fiat alternator light" you will find other people with same issue(red alternator light + no power steering). It looks like your cars ECU is fussy about alternator specs. Maybee your alternator is "over charging". I'm guessing these are mechanisms to protect the electric steering.
