    Dimming after revs ?

    hi all,

    another little problem with this car of mine i'm trying to iron out. I was out tonight fitting a new thermostat tonight when i was giving it little rev's to warm up the car when i noticed the instruments and headlights dimming after the revs dropped not too sure what this could be? maybe alternator or battery problems?

    i've uploaded a vid of what happens to youtube to show you what happens heh

    I wouldn;t worry about it TBH, mine does that too

    If your that worried about it check the battery voltage with the engine running and the lights are on

    Or get a clamp meter on the alternator to check the output, as the previous poster said mine does that too, although on my old rover it was a sign the alternator was dying.
