AAAck! Please do not. Unnecessary butt crimps just ask for future intermittent connections. (as it is) Bolted ring terminals are so much more reliable.

NONSENSE!!!! Properly crimped and sealed connectors are the most reliable way of joining two wires. Problems only occur when done improperly, usually with inadequate force or a poor crimper. For larger cables like that shown I use a Thomas & Betts crimper (2ga-8ga), an electrician's tool.

Posts are good as well, but the cables must be secured such that sideways movement does not loosen the nut.

Fuses always should be in the positive leg. Not sure where you got the information they are in the negative in Canada.

It is an ANL fuse holder. They are used for DC only, not AC.

Indeed.

This might work better and avoid possible confusion ...

Indeed. I fail to see how the crimps themselves on a single butt-splice is fundamentally any different than a pair of bolted and mated ring terminals.

A crimp is a crimp if done properly. The bolt may loosen on a pair of bolted ring terminals if subjected to enough strain or vibration, while on a butt splice the two crimps are essentially on the same tube of metal.

On a negative-grounded system putting the fuse on the negative leg will protect against overcurrent on the circuit but fail to give any short-circuit protection on the wires unless there is also a fuse on the positive leg as well.

I have never seen a type ANL fuse that was listed for use on AC, but I am not sure if this is an absolute. The form-factor was designed initially for high-power audio systems.

The positive may be (no reason to doubt you) but the negative cannot be from or to the battery selector switch.

Put a label on it and leave it as is.

Re: mystery - electrical connector

that type/size of fuse would have been used for either a heavy current draw windlass, bow thruster or even supplied the op voltage/current to a SSB.
