The cupboard which holds the ehu in has a light which was not needed and in the way so i removed it, i may well have caused a quick short. During this i heard the CD whirring(powering down i guess) and then later found its dead aaarrrgghhh. Its connected to the reversing camera and 10" screen for watching dvd's and doubles as the reverse camera screen all factory fit. So the radio is dead as is the screen so thought blown fuse, checked every fuse in the vehicle without success. I noted though the trip on the ehu (can't remember its name) had tripped so i did short something, reset that and everything works fine bar the Radio/screen which is 12v. I even pulled the radio to see if it had its own fuse but no joy. Any thoughts on where else to look ? 2007 Renault Master base if it helps.
