64 coil wiring question

Recommended Posts

Hello Buick Scholars,

I'm having a bit of a troubleshooting problem. I have a 1964 Riviera, fresh engine rebuild, fresh distributor rebuild, carb refreshed. I can start it cold and it starts right up. Warm it up, take it for a spin and it performs flawlessly. Let off of the throttle and it dies.... and won't restart. Unless you put twelve volts to the coil from the battery or alt. doesn't matter. I'm running a new pertronix coil and ignition. Unfortunately I don't have the original coil to test. What do you think I should do next?

Thanks

Kraig

Contact the tech support at Pertronix and ask them. Chances are it has to do with the voltage you're sending to the distributor.

I don't use the Pertronix ignition, but I think they want it to get full 12 volts all the time. The factory wiring has the power feed to the coil going through a resistance wire to knock the volts to the coil down while running to about 8 volts. So that might be your problem. Check the Pertronix documentation.

What is the stock voltage to the coil?

Thanks

About 8 volts while running.

I ran my '64 with a Pertronix coil and ignition with the 8-10 VDC for a while with no problems. I since am using the 12-14 VDC that they recommend. Might be a temperature sensitive secondary winding in the coil. Swap out the coil first.

Make sure the rocker arms are not too tight and that you are getting lubrication to the shafts.
