Hi,

I am being driven demented by an intermittent electrical problem on my 2004 Ford Fiesta.

The IGN fuse regularly blows while I am driving (on average once every three or four days).

I took the car to an auto electrician and he said the IGN fuse on the Fiesta is used to protect more circuits than just the cars ignition. He said according the wiring diagram a problem with the break lights could cause this fuse to blow. He noticed the break\driving light bulb was broken with filaments touching and suggested this might be the problem. The IGN fuse blow again the next day. I've since noticed that the break lights are on a separate fuse (labeled STOP), so the electrician must have been just chancing his arm.

Has anybody here any experience of this sort of problem or any suggestions what I should do next?
