70 up charging system upgrade question

4spdragtop said
Car tries to start when I release key. In start it just cranks.
A test I ran earlier gives 10.80 v at coil cranking.
This is a 1.70 Volt drop??
Notes from more of today's tests/results.
Thanks
Steve

Steve. That all looks normal to me. I bet the voltage at battery when cranking is right around 11.

Is the problem that the engine won't start?

And this happen after changing from a positive regulator to the later negative type regulator, or is it seperate?
