Looking for Ford Fiesta 2003 Electrical circuit diagram

Hello all

I own a Ford Fiesta V 1.3 i 70cv of 2003, only 55 000 KM (34 000 MI), that is in a very bad situation.

There is a shortcut somewhere in the electric circuit that burst the motor controller when switching on.

I've already got around the controller obsolescence problem by finding a repairer. Now the last chance before taking the car to the scrapyard is to find where the shortcut comes from.

Does anyone would have or know where I could find the electrical circuit diagram please ?

Best regards

Cedric

    To identify the circuit is there a specific fuse that keeps blowing?
    I assume your terminology of 'motor controller' is the PCM located in the engine compartment, front of the battery?

    I'm not even yet at the point of looking at the fuses.

    Sorry, I don't know what is a PCM, all I can say is that what I call a "motor controler" is in charge of igniting the engine.

    Thank you but I just had a look, it seems they have nothing for Ford Fiesta between 1997 and 2006.
