2007 grand caravan won't start brand new battery, clicking sound...

[Rickkins]

Hi guys.

So, like the title says, I go to start the van this morning, and all I get is a clicking sound. Everything comes on, radio lights etc,

Battery was replaced a couple months ago with a brand new "Kirkland" battery. All connections were cleaned at that time.

Failed to start even with my battery charger, which has a boost function, hooked up to it.

Where do I start...???

Thanks.

I tried the starter relay jump trick, connecting pins 30 and 87, same loud click, which on the surface seems to be coming from the starter.
