Bad starter?
Replaced the starter on a 1994 F350, 5.8L, 4x4, standard cab less than six months ago. Since then, I've only started it probably 50 times. When I turn the key, starter makes a clunk sound. I cleaned all connections and grounds and terminals, no change.
So, I pulled the starter and hooked it up to a battery charger, + side to the little connector on the solenoid, the - to the case of the starter. Armature will kick out and retract but will not spin. Does this mean the starter is bad?

Well.. how big a charger? Starters can draw lots of current, up to several hundred amperes under load. If hooked up to a proper battery and it still won't spin though, then yes it's likely junk. I'd still want to test it a little more thorough at a shop or parts store though.
Have you tried putting the charger on the battery?

I tried it at 2 AMP, 12 V fast (can't remember the amperage) and 75 AMP. Gesh, the original starter lasted 20 years, the new one six months. Crazy.

Hm. Well AMPS is the amperage. 75 maybe should do it free spinning, I dunno.
Maybe not though, due to the way a modern charger works. Use jumper cables and a battery. Or better take it in somewhere for a proper test.

There's your problem. The little connector on the solenoid is for the solenoid coil. You ALSO need to supply power to the big terminal on the solenoid since that is what powers the motor.
