    Hello Phil,
    Thank you for your reply.
    All we do is want to find out what was wrong.
    As we can’t see how it is, it’s hard to make sure whether it is the item problem or other problems, for example, the wiring, the load and etc.
    Or is it convenient for you to take some pictures to show the wiring?
    And please let us know more details about other parameters.
    We wil try our best to find out solution for you.
    Best regards.
