My 1970 Dart had an electronic ignition conversion done in 1992 using the single ballast resistor not the double. I have been having problems with it just shutting off or not wanting to start recently. I had no spark. I was checking voltage at different locations and going by wire diagrams to see if the wiring was OK. I found the bad connection. But in the process I realized that the wire run wire and the start wire to the pin on the ecu were backwards. It is drawing power through the resistor when it is running and it draws power direct in the start position. According to all the diagrams I can find that is wrong. So my ballast resistor is powering both the coil and the ecu in the run position. In 30 years I have only had to replace the resistor and ecu 1 time. Only driving about 1000 miles a year.
I am thinking I should rewire this thing the right way unless I am missing something? Does that sound right?
