Hi Mike,
Some radios have a fuse in the back of the radio itself, and others might have fuses inside inline fuse holders ( like the ones in the trunk for the tail lights ). Both types would require removing the radio to change.
I think there might be another fuse on the circuit feeding the radio as well but don't have my books on hand right now to check.
If no one else replies I'll check my manuals and post back.
Cheers,
Brian

Two fuses, typically. One for actual radio operation and one with constant voltage for the memory.
The fuses might be behind the radio, as mentioned....and possibly reached by removing the LH 'cheek' panel. More commonly, in my experience, they're found in the vicinity of the LH ashtray. Removing the ashtray might reveal them but removing the ski slope console panel is a surer bet.

red wire from the radio harness connects to the brown ignition switch wire,
black wire connects to the a/c evaporator case with a screw. It also has a fuse.
yellow wire is for the station memory presets
all three wires are normally located behind the driver's side "floor vent" panel. Remove the two vent screws and plastic vent fascia then pull the upholstered panel towards the front of the car to release two clips.
I posted a scan of the original Series 3 wiring instructions in another posting.
if all those factory wires and fuses check out , then your radio might have another modern fuse attached to the back of the radio. To check that fuse you will need to pull the radio out.

you will need to follow the service manual steps, it is a complicated set of steps if the radio is behind the a/c controls panel, unless your radio can be pulled out from where it is.
the radio in the pictures appears to be mounted on the outer surface of the a/c panel and that means it might be easily pulled out provided you have the pull-tools that come with the radio. All DIN-sized radios come with pull-tools. Your radio is DIN sized. DIN means that the opening is a rectangle. You insert the tools one on each side of the radio and pull the radio out.

Seem’s the early radio’s we’re fused behind the left side heater vent. The latter had wiring which extended further to encompass both sides of shifter. My repair noted their is an ignition controlled relay on the right side of shifter(small blk. box)and a noise suppression box(larger blk.). Noise suppression box was proprietary for THAT PARTICULAR Jag radio(maybe yours?, but doubtful the problem), I removed it because modern radio’s don’t need it.

This is the journey….Relay Black wire grounds to bolt on side of shifter with small nut. Brown12v from firewall behind glove box flows thru 20amp fuse behind rt. side heater vent connect to input of relay. Purple wire connected to same Brown wire at the relay input to provide constant radio memory. White/pink ignition wire(fused under driver side)activate’s Relay, Brown flows thru to output of a Yellow wire to power radio. I originally replaced the 20amp fuse, radio fuse driver side under scuttle AND the radio’s fuse on left side of shifter(radio’s wiring harness and got ZILCH! Bought a standard 4-prong relay and “She’s Alive!”. The wiring color scheme may vary from radio to radio, but the basic power scheme is Brown12v(constant fused) White/pink12v(ignition fused)Radio memory is spliced into Brown12v(constant), S(grey) is radio dimmer and of course my problem was the $8 4-post ignition relay. Good luck.

Well, all I can add to the issue is that before VIN 366291 there was a radio with very little wiring which would explain the 1 fuse behind the left heater vent and after VIN 366291 a more complex radio wiring diagram, ie: noise suppression box, ignition relay box. As the picture shows, all that radio hardware cannot fit behind the radio panel which would explain why it is located on either side of the shifter. I know my radio was not an aftermarket install because there is a large BROWN factory fused wire snaking down behind the right heater vent which ends on the right side of the shifter. The radio which you are referring to has a fuse behind the left heater vent. I believe as series 3 production progressed Jaguar used a radio requiring more power(current) which necessitated a larger power wire and an ignition relay box to control it. It’s in the PICTURE. I ain’t the engineer, I just open/remove panels like everybody else and post what I see and what I did/do about it.😁😆 1984 Jaguar XJ6, built in 1983 VIN 3830@@.

That's why I try to avoid going out to the garage!!! Got out there, started staring at the car, looking at it from different angles. Then forgot why I went out there. Damn Jaguar Mystique. Anyway, Jose I knew my car was late 1983, didn't realize HOW LATE. 02/1984. Wow, explains it, huh?
Seems the earlier radio's had a 5A fuse, then as the diagram show's, they used a 20A fuse to power the radio, nuttin else, just the radio.

It’s registered as a 1984. Strange that the build is 2/84. Purchased 5/84 with 75mi.
Wiring preference? Well, you know we prefer what we’re familiar with. I ABSOLUTELY prefer the wiring in my 84XJ6 than the wiring in my wife’s 2011. If she has an electrical issue with here ‘modern’ car…We Are Selling It.
