I have a 1996 XJ6 VDP. One day (about a month ago) after a rain storm, I went to my car to get into the trunk. I pushed the trunk button and nothing. Zero acknowledgement of any kind of power. OK, so I opened the drivers door, and pushed the trunk "tab" next to the left side of the steering column. Again "zero" acknowledgement of any kind of electrical power, Hummm. OK, then I decided to get the key, and start the car. As I put the key in the ignition and turned it, (again) nothing!

No dash instruments, no lights on, Nada, nothing. I'd just been driving the car two days before and all was good. With a key I was able to get into the trunk, and the battery is fine. Reading another post on this site, I've suspect that it could be a relay that's failed. I've ordered a (digital) work shop manual in order to figure this out.

A few days before (and one or two times in the past) when I started the car, it had a "transmission" light come on, on the left side of the instrument panel, and the car would going what seemed like a "safe mode".

Simply turning the ignition off, waiting a bit and re-keying the ignition and this "safe mode" and trans idiot light would have gone away, and all was fine. This happened about 3 times in 6-8 months.

When I original got the car (8K ago) it was having idling issues that seemed to have been solved by running Marvel mystery oil in the fuel. After about 6 tanks of gas all idling issues were gone, AND was getting 27 MPG on the highway.

At the moment (and until I get a manual for it) it's like a stone, There is no (absolutely zero) acknowledgement of electricity through the car, so it has to be a primary circuit, and when I read the posting (and answer to it) about the possibility of it being a relay, I've decided that when the manual comes, that's going to be my starting point.

ANY and all help would be greatly appreciated.

Thanks

First thing is to check battery for condition INCLUDING load test regardless how new battery is. Then check items in pics. Also you will probably have to reset security system due to not anything working.A test light and or volt meter is best to test fuses.

Thanks for the help. I have a load tester, and all the rest. I'll give allof your suggestions a go this coming Sunday.

Until I get the manual that I've purchased, I've no idea as to how to reset the security system, but I'll work on that too.

Thanks for your help.

OK, It looks like I have (thank God) a dead battery. After disconnecting the battery (and because the VOM was closer than the load tester) I tested for continuity across the 250 amp fuse. All good,

Because I was there with the VOM in hand, when I tested the battery with it, it showed power. Then I made the walked, and retrieved the load tester.
Then I put the load tester on the battery, and by all indications my (former) battery was just a block of lead. LOL. I'm currently charging it to see if there's any life in it at all, but (really) it's just time to go pick up a new one.

I'm suspect that this was the problem, and I hope the "only" problem. Thank you for your help. I really appreciate it.

I've owned the car for about 11 months, and had no idea as to age of battery. After a 6 hour charge, and still getting a "WEEK" indication on the load tester, I bought the BIG battery from Wal-Mart. It was $124.00 and has 900 cold cranking amps, and 1,100 warm cranking amps, with a 5 year warranty. A pretty good deal.

I'm a 20 year jag owner, and I also have a 1990 XIS-Convertible, and a 1971 series 1 XJ6 that I've worked up to. About 290 HP. ALL Jaguar. Ported Head, with 1 7/8th's Rob Beaher (racing)tulip shaped valves, and a triple (HD8's) 2 inch carb set up.
