you have a parasitic draw on the system. You will need to meter the battery draw at the battery terminals, while pulling fuses from the fuse boxed...one at a time.
Do you have a meter?
Do a search in the XJ40 archives with the words "parasitic draw" as part of the search parameter. Myself and others have written in detail how-to find the circuit causing the problem.

I literally just went through this with my XJS. It turned out to be a bad battery. Darndest thing. I could charge it, car would start great. But let it sit overnight, and it would be down to something like 7.3 volts overnight, but never flat dead. After spending a lot of time tracking down everything else, I took the battery and had it tested. Exactly my problem.
