Radio, interior lights and clock???

Hi, i am not sure what i have done?

I was trying to replace the stereo in my disco (n-reg), it had a kenwood in it when i bought it, which never worked.

anyway didnt have a clue which wires went where, managed to get the new stereo to power up and the electric ariel was working aswell, but now after fiddling, there is no power to any of the stereo wires, the interior lights dont work, the clock dosent work, although the clock face illuminates when you turn the lights on. I have checked all the fuses and they are all ok.

incedently, not sure if this is linked, but when the ignition is on there is a high pitched buzzing noise coming from the left hand side of the engine, cant seem to locate it -v.strange.

Could it be a relay,(one of the ones in the front n/s passenger footwell???

I put a meter across the interior light bulb and get a very small voltage?

any help gratefully received

this help?

sounds like youve blown a fuse, have you checked them?

i have checked all the fuses under the steering wheel, and they look fine.
thats why i was thinking could it be a relay???

i will follow the wiring diagram tomorrow and see if i can figure it out.

cheers

The fuses might look fine but check them for continuity with a meter if you got one

cheers guys, it was a cheeky little 20amp fuse in sattelite board under steering wheel. No.6 holder marked AUX and trailer lights - as I found out also does clock radio and interior lights!!
