801 will not start

I have a 801 ford with select o speed transmission. I had this problem on this site befor but have more information and need more help. my problem is i cannot get the starter to turn over. first notice the wiring and the key switch was getting hot with key off. when trying to start solenoid would not click. So far I have replaced the key switch starter button light switch and traced the wiring down and repaced bad wires and done continuity checks. Have follow tests in service manual but my mechanic ability is not the greatest so may not be accurate. hooked up starter direct turn engine slowly, took plugs out like book said did turn faster. I would be happy if I could even get the solenoid to click or get it to turn over with the key. my concern is with the wires getting hot and the solenoid not clicking. also could the safty started switch in the transmission be the problem and how do you test it. also could the starter have a short causing the wire heating problem maybe i need to take it in and have it checked. any suggestion would be appreciated.
 
1) The only thing the safety starter switch mounted to the transmission does is ground the solenoid (relay). To see if it's working hook one lead of a volt/ohmeter (set to Ohms) to the wire that comes out of the switch and hook the other lead to the transmission. Push the starter button and your ohmeter should go to 0 indicating a complete circuit.
2)Yes, if the starter has an internal electrical problem it can overheat the wires. Take it to a good starter/alternator/generator rebuild shop (I don't trust the 18 year old kids at Auto Zone to test anything) and have them test it.
3)I assume you have checked all wiring connections for clean, tight connections and that there is no paint on the starter housing or the transmission housing that would prevent the starter from making a good ground contact with the transmission.
 
I am a bit slow here. When using the key and starter button - nothing happens. When just sitting there the wires and switch get hot. Direct connection of the battery to the starter makes it slowly turn.

If that is correct, it sounds like you have multiple issues. First, buy a wiring kit. You can get one from this site. Replace all the wires. It will take you about 2-4 hours depending on how slow and careful you are. It's not a race - go slow and be careful.

Take out the spark plugs and rotate the engine by hand. Turn the crank pully. You should be able to spin it pretty easy. It may be turning slow due to engine damage. This will quickly show that up.

As others have said, have the starter checked. Then replace the thick cables on the battery and to the starter. Use #2 cable, not the less expensive #4. Sand all the paint off of the starter mounting area and the bolt ears on the starter for good connection.

Check the battery voltage - should be 12.5v. If not, charge the battery up. If it won't hold charge - replace.
