    Hi All!!!
    If anyone remembers, I have done electrical installation on this loader a while ago, there should be a thread about it somewhere. Now that is finished. Loader was in operation for 2 days without a problem.
    Today, bucket doesn't work. Boom and everything else works fine. Bucket can not be curled. I move joystick to the left, it dumps, I move joystick to the right, it dumps again. I can only curl the bucket by putting it on the ground and reversing while lowering the boom. And then I can lift the boom again, bucket doesn't dump by itself, it holds position, but no matter what I do with joystick, it dumps. I have noticed that it dumps slower when I put the joystick in curl position (left). I think that something is stuck or broken in the distributor / valve. I have no other ides.
    Any ideas what to test before I start removing whole valve assembly out?
