Drain on Battery 1994 -- XJ12

Drain on battery -- 2 days to go dead -- Taken out all fuses -- still a drain -- disconnected the alternator -- drain still exist -- any suggestions?

I put a test light in series on the negative cable the light is on, indicating a drain. The first fuse I pulled was the dome /cabin light fuse, so I could leave the doors open while doing the checks.

I was told to- re hook up everything and still see if there was a drain. Because everytime I turn the key to the on position the computer will take  30 mintes  to  shut down. Is that true?

Thanks for any suggestions!!

If you are leaving your doors etc open, pulling the fuse for the lights won't help. You also need to latch the doors so you can leave them open without the car knowing theyare open. I dont trust the test light method. Use a meter in series and should have no more than 0.3 amps after car goes to sleep. Once it is asleep if you have over that, start pullingthe fuses 1 at a time. Start with obvious things such as interior lights, radio, instrument pack etc. Once you pull it, leave it out until u are done so you dont wake up vehicle again.
