I can't give you details because I am not qualified, but I believe that he said the current magnetic pickup coils are to be built for .02-.05v somthing or other. The old style pickup coils were built closer to the .05v range and all of the newer coils are built closer to the .02v range due to being cheaper to build. His prototype testing was done on a .05v unit and when the .02v units hit the market is when he started seeing more issues with the no start. Then he worked with his vendors to come up with the added amplifyer solution.
Don at FBO can give you all the details. I am just trying to give some information on what happened on my issue. I just appreciate Don upgrading my existing equipment to help me fix the problem.

I attached a schematic that I have referenced in the past and it was not intended for a 70 application like I have. It was only intended for a quick reference.
Thank you very much for the detailed write up on the no spark troubleshooting and your schematic is a good one!!

You are quite welcome. I have been looking for that spec for a while. Thank you.

I left out one test, checking Coil - for power while cranking. You need an assistant, some body like the neighbor or in-law who never returns tools, or the EX. Make SURE you put your spark tester on the wrong end of the coil wire for this test. Jack up the car and lower the hood to get the geometry right. ...

Can any body identify this test equipment?

I'm thinking that a healthy pickup will generate ~1 volt AC on your VOM while cranking. Seperate the 2 wire offset pickup connector & connect to the pickup side & have your neighbor crank it (dont let the male terminal of the other half of the connector touch a ground while it is dangling). EDIT above pic, portable ECU/coil/ballast combo to diagnose the system or hot wire it for a test drive.
