I used to do +100 Amp connections. Crimps were never good enough.
Soldering was always better. Solder is not a good mechanical connection.
We always crimped first for mechanical then soldered for electrical.

and that's why it was getting too hot. So perhaps another alternative is like
the first (clean and put back together), only this time, solder the two
together; my intuition says that would increase the amount of amps it could
carry - or am I totally confused there?

Solder helps keep things mechanically sound, but for high current connections a well
executed crimp is probably better.
What I would do is pull the old lug off, clean off the wire, and crimp on a new lug with
a good quality (commercial grade, not Radio Shack) ratchet crimp tool. If it?s done right
it should be on very tight; if you can pull it off without serious force it?s either the
wrong size lug or the wrong tool.
