Continuing to experience weak starter motor when engine gets up to normal temp and run for extended time. I cleaned all connections from battery to starter motor. Only does it when engine is hot. Any ideas from the experts. Today it acted like I had a dead battery, but after it sat for 10 min, it started. I am puzzled

I'd tend to look for the simplest solution first. It may very well be the starter itself. As you'd cleaned the connections well, then my next move would be to have the starter tested professionally and rebuilt if necessary. Not turning over hot may indicate loose bushings causing a drag on the armature. Did you clean all of the paint off between the starter and oil pan? Ford masked these adjacent areas for a reason Has this issue been going on for a while? Getting worse over time? Or did it seemingly happen "overnight"?

In that case, I would most definitely eliminate the possibility of a worn starter. When you reinstall it, be certain all paint is removed from the adjacent surfaces - starter end / oil pan.

I would also suggest you put a voltmeter on the battery take a reading cold before starting, warm after running for 10 minutes with the engine running, before trying to start it hot and finally hot while trying to start. Check for any hot battery cable terminals also.

I have to ask,what condition are your battery cables?Are they large gauge?My 1952 Ford truck did the same thing and I could never understand what was wrong until I discovered the cables were corroded " internally"! I even took my starter off ,had it checked and rebuilt and problem was still there!

I second the comment about the cables. You need the proper sized cables and check for any corrosion. The braided ground cable is usually the one to cause the problem.

Did you complete any of the tests that I asked you to don in your previous post on this problem? If so, what results did you get? https://www.earlyfordv8.org/forum/viewmessages.cfm?Forum=14&Topic=15119&keywords=
