It was a good weekend for working on the Packard. I got a number of things done.
Although there may be a couple issues with the electric on the EC, I went through and performed the mechanical adjustments for the clutch and had great results. Everything (almost) now seems to be working properly on the EC. I can start the car in neutral, shift into any gear without touching the clutch, start from a dead stop in reverse, first or second, and go through the gears and everything works well with one exception. When it is time to upshift, there is a short delay between letting off the gas and engagement of the clutch. The result is a little slowing action as the trans starts to slow the car. It appears to me that either there is an adjustment I need to find that engages the clutch more quickly as the gas is released, or the trans should be free-wheeling at that point. Is it necessary for the EC to work properly that the OD be engaged? In that case, the free-wheeling action of the OD would address the situation. I don't see anything in the manual that says they need to be operated in tandem but I belive that the EC was only available on cars that also had OD. As an update to the electrical tests, upon re-checking, the low/reverse solenoid test (solenoid and circuit, not the switch) failed. I do get positive results that the windings in the solenoid are continuous, but I get no light when in first or reverse (or any other position). Not sure how definitive this is, given that everything seems to be engaging and working pretty well. I could not pull the governor this week end as it requires a very large and fairly thin wrench and I had nothing that would fit it. I did not want to use anything that would apply pressure to the sides of the unit, so it'll be another week before I get the time for this. Less luck on my OD this weekend. I am starting a new thread on that as it seems to be independent of the EC at this point. As always, all input and insight is really appreciated. I feel like I am making some real progress and having a lot of fun doing it.

Your persistence with the EC is very commendable!! Many (myself included on my 48 Custom) would have just shoved a cork into the vacuum line and pulled the fuse after that amount of effort. Now you've really got something unique that you can demonstrate. Of all the EC-equipped cars I've ridden in or driven, I can only recall one where the unit worked flawlessly, that at the 2001 Canandaigua PAC National, and I was really impressed. Kudos!

Thank you. I really enjoy working on the Packard and getting things to operate correctly.
This forum is great for undertaking these kinds of things because it really makes you feel like you have a deep bench and don't need to be afraid to move forward. Reading manuals is great, but direct interaction really makes things seem a lot less daunting. I really thank you for all your input because it is so helpful and your knowledge of these cars is amazing.
