I have a uk spec 1989 3.6 XJ-S.
Fuse 3 seems fine, though I changed it just in case, but to no effect. It also serves the boot lights, which are fine. I have had the ski slope off and …sadly there seems to be no fuse under there (I had been advised there might be). Neither are there any fuses under the console side panels (the parts with the vents in the footwells).
I have taken off the aerial relay and with power got the aerial to go up and down, so I guess that works.
Help please!

Thanks

Fuse Holder is the White Plastic 'Thingy' right at the back

But if you or anyone else wants to see all the wiring or How to fit an Aftermarket Stereo I have done a Full Write Up on this, including all the Photos you are ever going to need on Page:20 of my 'Cherry Blossom' restoration thread see Link below

Removing the Jaguar Radio to fit an Aftermarket Stereo in my 1990 5.3 V12

 

I'll have another look.
Thanks

 

As Orangeblossom says, you have to remove the radio case, which means removing the heater fascia, to get at the line fuse to the radio.

 

There are 2 inline fuses for the radio. The one OB shows (20A) and another (2A) in the centre console.

You say the clock is not working do you mean the Trip Computer? because the fuses are not common for the TC and radio.
