    I have a 22 hp liquid cooled Kawasaki with approx. 1700 hr
    the motor runs good for about 2 hrs if i put a new battery in it or charge the old one then it starts to run like #*^$ and shuts down. :cry:
    a short lesson on how the motor charges the battery would be great.:confused:
    if any one knows how to trouble shoot and or fix the problem this would help me a great deal.

    thanks in advance.

    First things first. Do you have and/or operated a DC voltmeter?

    Posting the engine model and spec numbers would be helpful so we can get on the same page.

    Here is a paste of a general test you can perform while getting numbers;

    Scag runner,
    Why are you looking for things to change out when you haven't even posted any voltage reading across your battery? You should have already tested your battery and voltages recorded across your battery at full throttle and posted something. Restrorob gave you a nice easy to follow diagnosis. We can't help you without numbers.

    i finally had time to trouble shoot the mower.

    when i checked the voltage across the the battery, their was only a little change across the battery at different speeds but it was around 12 volts. I checked the wires that come from the black box on the lower left side of the motor, and they were around 12 volts at different speeds.
    I did check the wires coming from the clutch, and the one with 2 black wires was about .13 volts
    And the one with the blue wire coming from it had about 8.56 volts.
    when i check the back of the amp meter their was always 12 volts even though it was on the negative side of the gage
