70 up charging system upgrade question

Got time today, I checked for resistance in coil+ wire with it and yellow at starter relay unhooked. With key in start. 0 ohms, so good there.
Checked brown "start " at ballast cranking, 11.24V, same as battery cranking, so good there too.
Removed tach wire from coil -ve to remove it from problem.
Reset distributor reluctor gap .008". New cap and rotor I ALSO ADDED AN ENGINE TO FIREWALL GROUND STRAP.
Fired right up!
Dunno what fixed it but all seems good "fingers crossed".
I had to reinstall headlight switch and ignition switch. Also splice taped a couple of connections from the MAD Bypass.
I rechecked and started the car after reinstalling every individual piece. Started normally every time.
I put a larger factory key switch plastic terminal connector on the back to help with tight connections. That made installing ign switch a pain in the arse!
Working for now, so line up storage and better planning for proper repair down the road.
Thanks all.
