An alternator can only create its rated output , they are not "smart"..

The smart voltage regulator is what keeps everything going.

A marine house battery smart V regulator is totally different in how it sees its task, from one for a start battery .

Sparking at the alt will instantly kill it as the load gets disconnected while it is putting out amps , which usually blows the diodes.

DO NOT turn off the battery switch while the alt. is charging.

Shut down the engine then shut it off , or you will need another alt. rebuild.
