I am trying to add an EMG 81 to my old epiphone, just one pickup really simple circuit. No switches, volume or tone knobs. I want to keep it as simple as possible. The problem is that the signal that comes from the pickup is very weak, as if there's no battery powering it. I've tried different combinations of the circuit, I tried another EMG, I changed a dozen batteries, but nothing changes. Why is that happening? I 've been trying to fix this for more than a month.

So your guitar has one pickup? No knobs or switches whatsoever? Did you replace the jack?
Fender '72 Telecaster Deluxe RI

Post a picture of your wiring diagram and a high-res shot of your actual control cavity, if you can. Hard to diagnose without any real information.
