Clicking under the hood

I have an 87 YJ, 2.5 liter manual. The other day I got in it and it started right up. An hour later, I went to start it and all I got was clicking ( click, click, click) and it sounded like the engine wanted to turn over but, just couldn't.
My battery is almost new and so is my starter. I tried to jump start it but there was still the clicking....

I eventually pulled the negative cable from the battery and reconnected it a minute or two later. The engine cranked right over.

This morning the engine turned over no problems, clicking, etc.
Later this afternoon it was very slow to turn over . It eventually did.

Any ideas or has anyone experienced this before? And what was the outcome?

Bad battery cables. Probably corroded on the inside. Easiest way to replace them is to get marine terminals and regular lugged cables. Going up a size or two won't hurt.

Bad connection. Take terminals off hit with some sand paper try again. Should be an easy, hope you resolve your issue.

Agree
It's either bad cables, bad connections or both.
I run two ground straps on mine, One to the engine and one the goes from battery to body to frame. Since a lot of years jeeps have the starter solenoid mounted on the firewall and don't have a seperate ground wire, If you don't have a good solid ground to the body it will act up.

Thank you for the great advice! You were all correct in it being the wires and terminals.
I replaced both with marine grade products and it Started right up.
