need help to identify

I was replacing the windshield washer pump on my 96 dodge van--and noticed something that looks like an old ballast resistor of sorts. It has what looks like three 4 gauge wires attached. It is mounted directly beneath the battery.
It appears to be cracked from age, heat, or too much current. It would seem to need investigation.

Looks like a bridge rectifier from an old-school charging system. But, I would have though more like that 1970s than the 1990s.

Other possibility is the speed-control resistors for the heating fan, but they usually live inside an air duct.

It is an electronic Battery Isolator (solid state, no moving parts).

Works the same as the Battery Separator, which uses a solenoid.
