Did you get the OD to work?

I have a 47 Packard with non working OD. As I look at the schemtic-it appears that all is needed to check it out is to ground terminal 5(Car off). I have been told by the previous owner the problem is in the OD unit. By grounding #5 it takes out the speed switch. Thus if it does not pull in it is either bad connections or bad pull in solenoid?
