Your eyes are infact better than mine. I see it now. So there's a noise suppression cap' there somewhere also. It has its own single wire lead with a male spade terminal. That is poked into the center one of the 3 females with the limiter. Those who lay in the floor, remove the drivers seat/whatever it takes, to reach under and blind exchange a limiter sometimes let that additional terminal fall out and leave it out. A loose connection can result since that female terminal did have 2 male terminals in it for a very long time.
the alternator and amp gauge...There is no printed circuit board connection there. These posts should not contact anything but the wires. Thus the isolators. Current path is ring terminal to nut to post.
