348 Wont turn off by key

Hi all, I have a 1996 348 Spider which seems to have developed an unusual fault in so much as at first, the radio & pod fans came back on, after key was removed (but then went off again after a few seconds) but this became more & more common, (and not going off) then in the later stage the engine wouldn't turn off when the key was removed either! so I had to stall it and use the battery isolator

Has anyone had this problem / can guide me in the the right direction? as I have had it into a performance specialist who has had it all over the winter only to ring me today to say he's at a loss and come & collect it!

We have tried the obvious such as Ignition switch & relay
So any ideas gratefully received !
Thanks Dave

Hi Dewa19 I have had a credible possible from another forum who has said to
'Check the wiring at the alternator plug. You may have to open the harness cover to inspect the wiring. I had one do this exact same thing to me. Drove me nuts for almost a week.'

Also another who has said 'Try disconnecting the radio, or pulling the fuse for it. The radio is a common point where ignition on 12 volts is present, and full time 12 volts is also present. A faulty radio or wiring could backfeed 12 volts to the ignition when the key was turned off'

Hope this helps
Regards Dave
PS. Take it you have already isolated the ignition switch out to eliminate that and also changed the relay?
