70 up charging system upgrade question

After cleaning up some bulkhead wires, (grey coil wire), ran new brown nss wire from starter relay. Old one was brittle and no continuity. Replaced starter relay(had new one on hand).
Batt static 12.14V
Key on "run", voltage test from run side of ballast harness to batt +ve with BR unhooked 11.18 volts.
Key in "start", measured same way but "start" side of BR, again unhooked, 10.20 volts.
Key off and I'm still showing 11.69 volts on start side of ballast?? Should that read 0 with key off?
I'm getting my "as built" schematic drawn out too(2nd revision) Tedious and time consuming but helps me understand having it all drawn out.
Should there be volts with key off at ballast?
Thanks
Steve
