Problem not solved. Car sat for 11 hrs. last night at the wife's work. Temp was 12 degrees, took about 6 cranks to start. (these are the details she gave me)
Odd thing is that I let it sit outside for about 8 hrs, in colder weather and it started no prob. pre new OVP 2 wks ago.
Battery, connections checked out OK and has a new OVP.
Maybe I should get the '69 Caddy out of storage and she can drive that!
