Does a solar charge controller have an internal fuse that can be blown? If so, can it be changed out like a fuse in an inverter? I purchased a new charge controller, all is connected properly but no LEDs are lit. My inverter is working fine, it has a display and it shows no charging taking place.Connection Diagram

It's fresh out of the box. Hard to return from where I am at. That's why I was wondering. I guess I can open it up.

Diagram shows controller connected across the battery jumper as a dead short.Controller should be connected to the same terminals as the inverter.Get the polarity right or the smoke can be released.Doubt it has an internal fuse.
