Re-reading your first post I see my confusion and maybe for others also. I thought you had a Pertronix “Ignitor” installed in your distributor. What's in the distributor now?
How bout hooking up the Pertronix “Ignitor” without the Toyota “igniter” like Pighead mentioned and how I also ran mine for years. With your 1.5 ohm coil you need to use the resistor. If you bypass the resistor, only do it for starting.
