Unplug your ESA to see if it is causing your problem.

Double check your plug wires, make sure they go to the proper plugs. I know it sounds basic but you should make sure the basics are sound before you go chasing zebras.

About the zebras, I heard a story that people right out of med school look for exotic diseases for symptoms because they are way more sexy than a common cold. So when a normal person hears hoofbeats, he thinks horses but recent med school grads think zebras.

Don't go looking for zebras until all the horses are accounted for.
