    Electrics shorting?

    i had a new alternator fitted last week as my old one was buggered, since ive had the new one my electrics in the car seem to fail when the engine is revved high

    i loose abs, power steering, engine, lights..pretty much everything

    the speedo goes dead and after around 5 or 6 seconds everything picks up again apart from my power steering, so i just turn the engine off and back on again n its cool

    although 2 of the 4 times its done it, its blown my headlights

    any ideas?

    sounds like you got the wrong alternator on your car. output voltage must be high to blow your bulbs.

    you 'might' have a diesel alternator fitted to a petrol engine.

    check the voltage output on the battery usein a meter. should not go above 14v

    i think the alternator has a regulator. that could be duff.

    either way DONT REV IT HIGH

    and take it back to the garage

    As above i'd get the new alernator checked out as it could be overcharging which won't be good for any of the systems on the car

    it may be a risk but get someone to measure it when reving high, see whats happening, it may be the case where the regulator is breaking down at high revs
