I'm hoping someone out there has a solution. I plug in my battery and all I get is a dim red light. No light no music. I tried plugging it in to the castle link and it reads it just fine, it says everything is ok. I take it back to the truck and I get the same dim red light...? Any ideas?

Are you sure you have the polarity correct on the plug from the esc in the rcvr? The neg (usually black) should go to the outside of the rcvr.

If this is right, its time to call Castle -
