I thought I would write an update to my GE 45T problems. Being frustrated by aftermarket 'repair' places and the sloppy work they seem to do; I decided to take the locomotive apart and try to see what the problem was. Cutting to the chase: One of the power leads (black) had become disconnected from it fastening point (as we say in Alabama; "It done broke"). I soldered the offending wire back where it belonged and put some tape over the end (did the same on the other wire (the red one). Tested the loco and it worked well. After reattaching the body (a 'fun job' especially those coupler pockets), I again tested the unit and [dang] it had a short!! OK, off came the body AGAIN. I lined the sides of the [metal] body with electrical tape, secured the TCS decoder and "Keep Alive", routed the new LED lights and tried again. Success!! OK, some 'take-aways' from this process: Make doubly sure NO wires can touch anything metal, secure any loose wires as they will work loose in time (I used a 'dab' of liquid tape) and very carefully reinstall the body. I hope this helps anyone else.
