Do i possibly have a bad pcm?

Lemme start by saying i have a 1995 eclipse and a 1999 eclipse which i work on both my self. My 1995 has some serious issues. Ive replaced my battery, alternator, coil pack,spark plugs and wires, and so on. Yet my battery light will not turn off. When driving at a steady speed the car will lose power meaning i can push the gas and nothing happens, when i let off it will rev and sputter sort of while this problem is occurring the battery light is off. I have taken my car to numerous mechanics who have no idea whats going on and try talking me into trying other parts which none help the problem. A friend said its not an electrical problem thats its my ecu/pcm, another local mechanic said he could not run a diagnostic because my pcm reaches 195 degrees. I dont understand why the pcm would cause my battery not t hold a charge. PLEASE DO NOT RESPOND IF YOUR GOING TO TELL ME TO REPLACE MY ALTERNATOR LIKE I SAID BEFORE, I HAVE DONE THIS.
