I have not been able to get spark and have now figured out the black white wire that goes to coil + gets .15v yes .15v when key is on start. It’s a points dizzy.  New coil. Points set. Green white to ballast 12v on start. Bw to other side of ballast 12v on run.  Is the problem coil wire running through the tach and running into a problem there???

This belongs in your other thread. It's best not to start a new thread for the same problem
