Ditto on the cables and wires. I have helped two buddies with similar problems and we rewired the TM. Upgrading to a larger wire size on older TM's makes a big difference in performance. Also check the wires from the batteries to the TM plug. Go as larger here as well, around a 4-6 guage works best in my experience. Good luck.
