video on YouTube or somewhere else so that I can get more info on what you mean by click-click-click.
There is a factory mode that makes the thing click about once a second, that if some how a pin was shorted, it could be in that mode.
The other thing that may happen is if the inrush current is so big from the click that it resets the shutdown controller. Knowing what you have behind the controller, the gauge of wire going to it, etc will help.
If you could provide pictures and take a video it will be much easier to help diagnose.
