Re: 39 Packard OD solenoid

I agree a lot of the drawings depict black boxes. I had to repair the OD kick down switch and relay so know what is in side them. I think I may FINALLY understand how this works.
In the dwg in post 22, the "boxes" depict contact points within the OD solenoid.
If that is correct, the HOLD in solenoid is always on with the ignition and when the governor is at proper speed and torque removed from the OD by letting off on the throttle momentarily, the pawl engages the planetary gear overdrive.
Either the early 39's were built this way, which logically does not make sense to me (why have a solenoid always active with ignition on) or over the years, a switch in series with the hold in coil was removed from my car.
thanks for all the help everyone, think I have it correct now, if not please advise.
If this is correct, I suspect I do have the two coils reversed as after the rebuild and rewiring, I see a large current draw when the key is turned on, perhaps thru the wrong could in the OD
