    Default Re: Questions - MOT failed

    Those volts are low for a car

    Should be 12v and above (unless your meter is suspect)

    Was that with engine running ?

    (Does it start ok by the way?)

    Can you confirm battery voltage at the actual battery ?

    The car wasn't running when I checked the voltage.
    The battery voltage is 11.88V, but the car always starts first time.

    But here is the weird thing.
    Some time ago I fitted an automatic light switch which turns on the lights in low light.
    This stopped working recently and today I remembered this and did a fault find to discover a connector had come undone.

    I replaced the connector then checked that the lights were coming on when the sensor was covered, and they did - so it is working again.

    At the same time I decided to replace both the bulbs with new ones, and the outcome was that both seemed to be at the same level of brightness (which looks the same as the 'good' one was previously).
    So I took them out again and re-fitted the previous pair - and the nearside bulb was dim again. So I swapped the two bulbs over - and the nearside was still dim. So I replaced both again with the spares - and they are both bright again.

    I'm not sure why that would be, but by default I think I have resolved the problem - only a visit to the mot centre for checking will tell.

    So now on to fixing the binding brake and the high emission issue before replacing the tyres.

    Thanks for all the input guys.
