Please Help with 04 Jaguar VDP XJ8 electrical problem ?
OK this is my first post here and I hope somebody can help me .
I have 04 VDP X350 41k miles with navigation . Problem I'm having is that car after it sits for 5-10 min will not run for long only 2-3 sec . I can here pump priming but after car starts it shuts off. Together with this my windows are not working fuel gage not working headlights not working and air . On the screen I'm getting message ignition off ac not available . After I leave key in ON position for 10min to 30min everything comes back on and I can start the car ,windows, air, headlights everything works as it should for as long as I keep car on as soon as I turn it off for 5-10min problem comes back . I need to know what controls all this together and if somebody can tell me where to look for a solution . There is no codes or bad fuses . Please Help

One thing that you will see in the wiring diagram is that electrical components work "backwards" from what people expect. Due to the use of power transistors, most stuff is "hot" (pos) all the time and the ground is switched on and off. It is possible that water got in somewhere and is messing with switching. Don't get side-tracked by the transport relay just after the battery. It isn't your problem.
