Yeld, you state: "if I put a small piece of wood between the contact points I have power to positive side of the coil and the negative side. But if I remove the wood chip no power to the negative side of the coil"

To find the cause of no spark if you work through my Ignition troubleshooting Procedure linked below it can help find the problem
