    Parasitic draw on battery. Have to disconnect battery every day or go flat in 30 hours.
    Right window only opens sometimes open with button.
    Need a new window wiper motor.
    I think something is up with alternator as sometimes lights flicker.

    Car is a 07 Honda accord 2ltr petrol. I say its worth 900 at best.
    NCT is up in July.

    Saving for a mortgage as well so thinking of just getting something new for a grand or something with a fresh NCT.
    A Micra would do at this stage until the mortgage is approved next year.

    It could be discharging back through the alternator.

    Here's a video, you could use a meter across the fuses.

    IMPORTANT: Move the positive probe to 10ADC unfused link (and dont forget to move it back when you are done!)

    Remove the earth from the battery - stick the multimeter to 10a and put the probes between the battery and the earth lead..remove fuses on a one by one basis until it drops to a reasonable level 0.02 = 20ma...average consumption should be 20 - 50ma!

    Once you've identified the circuit you can conduct your own investigations such as unplugging things until the ma read goes down. In my instance the issue was a water logged alarm siren, so as I unplugged siren it dropped to usual levels.
