Hello i have a problem and dont know were to start.

My jaguar x type 2008 2.2D dont have any power to the fuse box inside the car.

But if i take a cabel and supply the fuse box with 12V the car works great.

Is it a fuse thats broken that i can't find? Or is it a relay? And what relay?

If you look at this link.

You have this picures were it say
"PASSENGER JUNCTION
FUSE BOX (FRONT)"
between the realy R4 and R5 you have this bolt there shuld be 12V but there is not. And there is were i can supply 12V and the car will work.

Any ide were i can start?

sorry for bad english from sweden.
Thx for any replay

 

Daemon, look in the engine bay fuse box at fuse F39. It is a 150 amp "megafuse". This is the fuse that transfers power to the passenger fuse box. I bet you will find that fuse is blown (can fail with age, not so much because it failed due to an over current condition). If the fuse is good, then I would be hand over handing the large cable that runs between the engine bay fuse box and the passenger fuse box. One of the two ends most likely came off. While possible, it is unlikely that you have a high resistance/broken wire in the middle of that cable. But, this would normally be seen by have reduced power in the car (ie, blower motor seeming to run slow even on max speed, lights dimming as more electrical load is needed, etc).

 

Daemon, note that in the later models such as yours, the mega fuses, including Fuse 39 are on the underside of the engine bay fuse box, so you'll have to unbolt the box and lift it to get to the fuse. F39 is under Fuses 16,17 and 18 that are on the top.

It would be sensible to disconnect the battery before doing that to avoid touching a live terminal to a ground with big sparks!

 

Wow fast answer you are right. The mega fuse 150amp are broken. At first i did have a hard time to find the fuse.

Thx from my heart! :-)
