    Gravely 987070 v twin briggs

    I have a 2001 riding Gravely 987070 16hp v twin Briggs. Battery does not seem to be charging. Battery tested good (one year old). Battery runs down when not in use. Terminals clean and tight.

    If you have a multimeter/voltmeter set it to DC voltage 20.
    Then with the mower running, put the + lead to + on the battery and - to -
    You should get at least 13.00 volts if the battery is being charged by the generator.
    Or it might be something else is draining it while sitting.
    I know enough to be dangerous
