V3.0 MS1 HEI to pertronix question

Post by willys59cj5 »

Hello,
Its been a long while since I messed with my megasquirt controller. I have been running V3.0 MS1 for 5 or 6 years on a GM HEI 4 pin. Fuel only no spark. For ease of setting my timing, I am changing the distributor back to the original delco unit, but using a pertronix unit instead of points. As I remembered running the tach signal off the GM HEI was the same as the negative side of the coil. I went back and looked at my V3 build and went through the build instructions. Looks to me that all I need to do is hook up my current HEI connection for the trigger to the negative side of the coil on the pertronix set up.
Thanks in advance for your help.

With a single coil setup, it shouldn't matter to MS how that coil is fired. As even points or any type of electronic trigger produce basically the same sort of signal.
