Going back to Chrysler ignition

I am in the middle of a no start when cold issue on my 64. It was converted over to Mopar electronic. I am leaning towards the starter draw may be excessive enough to draw the battery voltage below the minimum for the ECU. (around 10.5v) I have a few components to try before I go back to points (and may be a Pertronix) or replace the starter. LOL
