I had a similar thing happen on my MGF and cured it by removing the 70amp fuse under the bonnet and cleaning the terminals. Was fine after that.I wonder if anyone could shed some light on a very intermittent problem I have.
When I say intermittent, this has happened twice in the past 12 months. The power steering warning light lights up and I lose power steering. I turn off the ignition, switch the engine back on and Presto, all is back to normal again.
Not much of a problem at the moment I know, but I don't want it to get worse.
