Red hot battery terminals

[Taxi_Driver]

If only one terminal is getting hot at a time....then Id say bad/dirty connections, high resistance so it gets hot.

If that amount of current was going through the battery......both terminals would be hot at the same time...and your battery would be fried by now.

Try cleaning up and retightening not only the main battery connections, but all the connections on the battery studs.

And the advantage for finding out what it is that the alternator would sell to anyone who had a knackered one

Maybe, only maybe, it's a poor connection on the engine earth strap... Once saw a glowing red accelerator cable on a Pinto,  simply due to the engine earthing via this, due to a sh1te connection on the engine...  Agreed a dodgy battery would be my favorite, however, electrics / electronics...  a mind of their own :-?

Sounds like a bad connection at the battery, take off and clean the terminals and refit tightly
