English term or phrase:electrical arrestors
Pourriez-vous me dire comment traduire ce terme en français dans le contexte suivant :
une voiture de police arrive dans une ruelle où un braquage vient d'avoir lieu, mais deux secondes après s'être engagés dans cette ruelle, le moteur de leur quatre-quatre s'arrête brusquement. On en découvre la raison un peu plus tard, c'est parce qu'ils ont roulé sur des "electrical arrestors" (ou arresters? je ne suis pas sûre de l'orthographe) Voici le passage dans lequel figure le terme (il s'agit d'un dialogue, série tv) :"I know why your cars shut down. Electrical arrestors. They short-out a car's electrical system when you drive over them."
D'avance, merci pour vos réponses.
I have some doubts; to start with, if I understand it correctly, this doesn't actually 'turn off' the ignition, but simply 'jams' all the electronics in the car — or at least, the important bits that make it go!
I can see this would easily be possible on a strictly localized basis, simply by producing a very strong electromagentic field that would saturate everything — rather in the way that a nuclear-generated EMP could wipe out electronic operations over a much wider area.
Is this science-fiction or not? I am not aware of such devices.
Some hints :
en lightning arrester
a device designed to protect the electrical apparatus from high transient overvoltages and to limit the duration and frequently the amplitude of the follow-on current

Difficult to see how driving over some device can "short out" a car's electrical system; but I've had three occurrences of my car engine cutting out when passing by an electrical sub-station on a motorway (it was confirmed that there was nothing wrong with the car). All I had to do to start the engine again was switch the ignition off and back on.
I could suggest "immobilisateur électronique", but this usually refers to an anti-theft device.
I'm willing to be corrected, but I think this is just a bit of fiction for the sake of the story.
