Battery Negative Terminal Overheating / Melting - '73 TX650

[Chrondor]

Hey guys,
Anyone have an issue with the battery terminal getting hot?
My first suspicion is the negative terminal may have been in contact with the seat frame causing some resistance.
Not trying to roast the old chestnuts here. Bike runs fine when it gets a steady electrical signal otherwise.
Put in a new Duralast Gold ETX14L and has this event with no issue ever with my other batteries over the years.
Going to try a new battery this weekend (not the duralast ever again)
Could this just be an incompatible battery type or ohmage for the TX650?
Any help or feedback is appreciated.

Wouldn't matter if the terminal touched the frame, it's negative ground.

Make sure there’s no corrosion on the ground cable at either end. Make sure you don’t have an excessive current draw. I use a test light. Disconnect the ground cable. Put the test light in series. The lamp should be off with the key off. Likely high resistance (corrosion) in the ground connection.

FWIW, NAPA and O’reilly AGM batteries are made by Deka in Pennsylvania. NAPA had my battery in stock a few weeks ago. That’s is it turns out you need one.
