    Battery draining - Aprilia SR MAX 300

    I am having a problem with the battery draining.
    I have replaced the original battery that lasted 4 years, I charged it a few times but then replaced it with a new YUASA. The new one now has drained completely after 2 weeks!!
    The voltage at times varies between 14.3 and 13.8 which I am told is good however on other occasions after starting up the voltage will only go to 13.3 and then drop to 12.5. Go to start it up after a few days and no joy.
    It seems that this could be a regulator problem, has anyone had similar issues?

    Cheers
    Mark

    check if your underseat storage light is on all the time, and take a multimeter and locate the drain

    Yes, I did check and the light is off when the seat is down.
