Charging problems 67 Barracuda

There are variations, not all of them "factory."

Below is a "hack" created by a "hack" of a so called rebuild shop. This has been a lot, way too much, and the thems that did it should be hung by the parts. What you see here is an original 69 alternator that has been drilled to accept an isolated brush to "convert" it into a 70 / later unit. The problem is, sometimes these mistakenly ALSO came with a grounded brush. This can cause problems!!

The factory isolated brush is at 9 oclock, the factory grounded brush is at 6 oclock, WHICH IS INSTALLED, and the "hack" brush which is missing is at 12 o'clock
