One battery terminal in my back battery pack is getting really, really hot when the tractor is being used. When it is not being used, it is not hot.
Loose wire. Heat comes from resistance. If there is resistance between the wire clamp and the terminal you get heat.
Pull the terminal off the battery, clean terminal and battery, re-install. Also check if the wire is hot; might be that the terminal-wire connection is bad.
