Hello,
I recently bought a Fiat Punto II 1.3 jtd 2005 and I have an eletrical issue.
Fuse F11 is blowing each time I turn contact on.
I replaced the fuse by a bulb, it lights immediately while turning the contact.
It seems to be a shirt circuit but I can't find it.
I disconnected egr and preheater but without success.
I can't find lambda sensor which is supposed to be linked to f11.
I can't find the exact list of what is connected to F11 fuse.

Does someone have a wiring diagram for my car to help me identify the instruments connected to fuse F11 ?

While using a bulb instead of the fuse the preheater is not working.
That's why I'm also interested by wiring diagram concerning the preheater.

I suspect there is a wire touching the earth or inside wiring harness but it's very difficult to find it whithout diagrams.

If any of you had the same behavior or any idea i would really appreciate your help.

Thanks

Solved

The diagrams I found where mentionning a tachymeter connected to F11 fuse.
In fact I found a plug just hanging. It is part of the wiring harness but note connected to the gearbox, since speed is measured using ABS sensors.
The wires of this plug were not well protected and were touching the engine and creating the short circuit.

Well done mate, glad you sorted it
