Fuse F16 40A feeding through relay RLY 11 in the engine junction box. If there is power going through then check the LH connector, probably in the ‘A’ post.

By all means have the battery tested though I would also be having the alternator looked at.

No need to remove the battery for charging. Connect the CTEK to the positive of the battery and the negative to a ground point and you’ll be perfectly ok.

On your car, positive to the battery terminal and negative to a suitable ground point.

That question I cannot answer unfortunately. I would hazard a guess at the bottom of the ‘A’ pillars inside the car.

The relays may well be the soldered in type below the grill in your picture. If you’ve found the fuses, switch them on and check for power at the fuses.

Right side is relay R13, fuse F7 40A and left side is relay R3, fuse F32 40A, both in the engine fuse box.

I see nothing on the drawings to suggest there is a light around the ignition barrel.

It looks like this is what you’re after. https://parts.jaguarlandroverclassic.com/xr82213-housing.html

To drain a battery that quick would require a huge amount of current. I suggest you do not connect another battery until you have carried out some fault finding. Main cables, spare wheel well, front water drains and then the various modules.

I would think you’d be looking at bespoke floor mats with all that on them. Try this place, https://www.mrcarmats.co.uk/jaguar-xkr-car-mats.html

You’re welcome, glad to have helped and thanks for the update.🤙

This may help,

Before you go bring stuff you may not need, check the inertia switch hasn’t tripped. Also check the fuel pump relay and fuse.

Have a check around the breakers yards in your area for a used one. Check also that the carpets in the footwells are not wet.

May just be your battery voltage being slightly low or a bit of moisture around the coil pack area. Either way, charge the battery first and then see if it happens again.

Do you have the x308 (steel version) or the x350 (aluminium version)? First place to check is the little flap in the ignition switch is closing when the key is removed. Next and most common, is the “alarm chirp sounder”. This has a rechargeable battery that leaks overtime and shorts out causing the drain.

Here’s one in Holland, http://jagparts.nl/catalog/product_info.php?products_id=8313 Maybe worth a call.

No problem, hopefully you can find the part you require.

A new one is £550 or you could search the breakers yards.

No matter what you do, it will get worse. The only way to fix it is to replace it completely.
