I have a 1977 Jeep CJ5 with a AMC 305 v8 motor. I am a weekend worrier when it comes to Jeeps. I replaced my throttle cable because it recently broke. It burned up upon ignition. The SST threaded cable heated up enough to catch the plastic grommet on fire. Know I know there is an electrical situation going on here but where. Anyone have this situation, if so how did you fix it?
