4610 starting issues.

I just replaced the starter with a brand new one even the solenoid. (Previously)It sounded like it would whirl over but not engage the flywheel. I could bump the key a couple times and it would eventually crank. My guess the abendix was going bad. So I just replaced the starter and now I have a click sound like a weak battery or bad solenoid. It will eventually crank but the positive battery cable will get very hot after about 3 to 4 seconds of cranking. Only gets hot while cranking very hot to touch. I took and changed the battery and same problem. I cleaned and scratched the cables off good. I even moved my ground to the base of starter mounting hole on the block. I did just replace the neutral saftey switch and saftey switch pigtail. It went bad over the summer and I disconnected it and used a small wire to close the circuit. Dont see that would make a difference.

Heat means you have a poor connection. Sounds like you've ruled out an issue where the cable end meets the post. That poor
connection could also be where the cable strands meet the crimp. To test, if the strands are exposed, put a voltmeter probe on
the cable strands, and the other probe on the terminal itself. You should have well under one-tenth of a volt while cranking.
Anything higher is bad.

If the cable end is covered up, which it appears yours is, test from end to end of the battery cable. You want less than five-
tenths of a volt (.5) for the whole cable. While you're at it, check the negative cable the same way.

Heat means bad, cable could be bad internally.

I would bet it was failing and you helped it along when changed starter.

Ok, I'm here now. That's kinda what I was thinking was the cables. I scratched and cleaned both ends of each pos and negative very well. I have a multi meter I'll check back in a little while and tell you what I've got. Thank you!

That cable has a big insulator on it. The wire could be corroded through underneath at the terminal. If so then would need to cut back the cable to good wire and install a new terminal end. Preferably a soldered connection first with a crimp connector as second choice.

Kept thinking I was having battery problems with my ford pickup when getting the clicking when trying to start and a battery charge always worked. Finally crawled underneath and found the cable connector was almost corroded through.

Ok, New starter is back on cables are definitely in need to be replaced. It started but is it went up to 16.6 vdc then dropped back off to 16vdc. I did just replace voltage regulator today.
