I want to share what happened to me, rather than posting a question. Went one morning, a week ago, tried to start the truck (1965 F-100 352 CI), no luck. It clicked, like it wanted to go, but no start. That evening I tried again, sounded like a "clunk" when I turned the key, but I got nothing out of the starter. Gave it a jump start with my little '83 Toyota Tercel, nothing. Got the wife's minivan, nothing. Got my multi-meter out, tested the battery and it read 12.7 V. Tested the solenoid (Which is fairly new, by the way) and I got battery power at the right contacts. And it click-click-clicked when I turned the key, so that told me that the solenoid was doing its job. Went underneath, and I was getting battery power at the starter. Still, when I turned the key, the starter clunked, but no turn. The lights went on, and seemed quite bright to me, so by then I knew the starter was the culprit. Went to the auto parts place, got me a new starter, and got it on. Happily, I turned the key, and all I got was the click-click-click, and then the "clunk". I was baffled. I went out and re-tested the battery and the solenoid, and I was still getting 12.7 or so V and the solenoid was doing its job. I came to the forum and found that the cables could be corroded and creating too much resistance. Mine were pretty corroded, so I replaced them all with new ones. Went back to the cab, turned the key and... click-click-click, and then a clunk. Now I was ticked. It does little to one's health to kick such trucks, especially wearing sneakers. Went and got into some youtube videos, and found someone saying that testing the voltage is not all, you need to test your cranking amps. I don't have that kind of tester, so I went to the parts store and got the battery tested.Turned out it was dead. "Huh" I thought, I charged it a good 20 minutes that morning. Well, I put in a new battery, turned the key and... Yeah! Started like a champ. I wish I had thought of that before throwing $200 at the truck, but it's a lesson learned. And I got new cables and a new starter, which isn't a bad thing. I'm still shaking my head at the darn cranking amps...

 

Aways do a 'Load Test' on a battery. Load testers are cheap. Do you have a Harbor Freight near you? Nice thing to have around just in case. Sorry you had to spend more than you need but glad you found the problem.
