Apparently electricity just doesn't function that well around
massive amounts of magic; it isn't something they do on purpose.

What about the Flying Ford Anglia by the way ? The fact that it can
run out of gas seems to indicate that it still functions in a Muggle
way, with gas and electricity. How does that work if magic and
electricity do not go together well ? And if Hogwarts completely
repels electricity, then Harry and Ron should not even have made it
to the castle in that car, it should have completely died before.

Arya Now:
In GoF (no books here at work), Hermione says electronic 
stuff/electricity does not work at Hogwarts when they are discussing 
possible ways that Rita is getting scoops (bugging devices, 
specifically).  

Also, the Ford Anglia did not necessarily run out of gas--in fact, I 
have always been under the impression that the fact that it goes all 
haywire when it finally approaches Hogwarts, was a direct result of 
interference from magic, mucking up the electrical controls and 
components of the vehicle.  (Besides, how would 12 year old Harry and 
muggle-dince Ron know what a flying car running out of gas feels 
like?)  I took this as a perfect example of what happens if an 
electrical-controlled artefact (albeit bewwitched) tries to operate 
around the magically-rich Hogwarts.
