Default Fairbanks Morse Mag Question

Ah the joys of working on things that you have never done before...I have two Fairbanks Morse magnetos, one on a Wisconsin AKN and on a AEN. Now the AKN mag has a red wire coming from the coil and goes to the points. Then a black wire to ground?
The AEN has the red wire BUT the black wire was just attached to the points and the other end taped off not going to any ground point. Is that correct? or does that black wire need to be attached to some kind of ground?

Thanks and God bless.

Grounding points is the kill switch.

All the black lead does is go to a kill switch that grounds the points. Just take it off or leave it taped .

Ok, thanks a lot. One of the reasons I asked was after installing and setting the points on the AEN's Mag, and I turned it over a few times, I notices sparks form the points! Hmmmm....

Ground the high tension (spark plug) terminal to stop it from arcing internally and damaging the coil.
