With the points closed you should not get any voltage reading on the points side of the coil as the current should be flowing through the points to ground and any voltage reading you get is resistance between coil terminal and ground. So, if your points are not contacting or open you will have full voltage readings. That is the fact of the laws of physics. Try this, with switch on, hook a small jumper wire,(alligator clamp type works good)to the points side of the coil. Now , holding high tension wire from coil about 1/4 inch from frame, touch the other end of that jumper wire to ground, should get a low voltage arc from that jumper wire, now pull wire away from frame and you should get a spark out of the coil. Just remember this principle, the points are nothing more , or nothing less than a switch that grounds the primary windings from coil and every time that switch opens, the magnetic field in coil collapses around the iron core in coil and creates high voltage in the secondary windings, thus a spark. You are making a simple problem way too complicated.

Today's Featured Article - Choosin, Mounting and Using a Bush Hog Type Mower - by Francis Robinson. Looking around at my new neighbors, most of whom are city raised and have recently acquired their first mini-farms of five to fifteen acres and also from reading questions ask at various discussion sites on the web it is frighteningly apparent that a great many guys (and a few gals) are learning by trial and error and mostly error how to use a very dangerous piece of farm equipment. It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
