1994 Ford Ranger Ford Ranger burning up starters and will n

I replaced the starter relay switch and had the ignition switch checked, both are in good shape. I do not get why the starter is kicking out and not kicking back. This is the third starter. All wires and fuseable links were tested and found to be fine. The alternator was tested and showed no problem, I am at a total loss trying to figure this out. I have the Haynes repair manual but still have the same problem. Any clue?

Yes I did the jumper test without using the key. It will start and run for a minute but the starter will not kick back and it is the correct sterter. I t is for a 4cyl, 5 spd. 2.3L. I still do not understand why the alt. Will not charge. I tested the two connectors on the side of the alt. And one wire shows the light bright and the other shows a dim light, the middle wire has nothing. The starter will start the truck but if I don't remove the negative terminal it will burn up another starter. Ignition switch is good, solenoid or starter relay is new, starter is new, battery is new, alternator working fine until you crank and start the truck, then the starter sticks. Touching the starter realy makes it kick back but still no charging. Could it be the connections on my alternator. How can I test besides voltmeter showing good and light test showing good. Have tried evreything and using Haynes is not helping. Where is my computer located on this Ranger? Thanks for any answers in advance.

I have am having the exact same problem in my 1994 ford ranger 4cly, 2.3, 5 speed manuel tran. I already tested the S terminal on the solenoid and it was working right.
Could someone show me how the solenoid is supposed to be hooked up that way I know mine is right?
If it is the flywheel, well then that really sucks.
Thanks
