I have a 81' bronco with the 300-6 and a manual trans. The problem is that I can't get it to start. I have replaced the starter, the starter solenoid(3 times) and the cables. Sometimes it will just click, and sometimes it will turn over very slowly. The cables and the solenoid get very hot, and sometime will start to smoke, or turn red. If I connect jumper cables directly to the starter it will turn over faster, but the power cable still gets very hot. I'm all out of ideas, and any advise would help.
