With the Key (Ignition) on, the Circuit should be from the I terminal of the key or ignition switch to the resistor. (resistors are sometimes integrated into the wire from the switch) there should be battery voltage there or ~6 volts if wire resistor. If 12v there, it should not have an additional resistor. From the resistor to the coil positive (if negative ground) there should be ~6v there if the points are closed. From the negative side of the coil there should be no volts if the points are closed. With the points open, there will be 12 volts even with a resistor). Most engines stop with the points closed, so there should be no voltage at the points connection (assumes closed points. If there is voltage there, and the points are closed, they are not making contact, clean them. There is never voltage at the center terminal it is connected, but has high resistance and will not show volts. Measuring from the coil negative to the center terminal with an ohm meter set on 10k ohm scale should make a resistance reading. Jim

Today's Featured Article - Threshin Demonstration - by Michael Delaney. Introduction I bring you greetings from Prince Edward Island, Canada. We are Canada�s smallest province but big on farming. Maybe you�ve heard of us. Potatoes are our biggest crop. However, there is lots of mixed farming here also. I have a small mixed farm with 25-30 cattle. I make very good use of old machinery. I have a 135 MF Diesel, Farmall H and 1/3 share in an Allis B. I have complete lines of tillage and harvest equipment, and a saw gear etc. I have everything one would
