Re: Overdrive wiring issue

I took the cover off the Governor today (of course did not have the presence of mind to snap a picture) and it does look like the screw in question does adjust or at least affect the top most point in the point set. Now that I see how it operates, I can see that screwing it in probably forced the points closed. Does not look like anything is bent, but getting the gap back correctly could be a problem. I can probably confirm that the governor is the issue by screwing this down again to close the points and using the dash knob to engage the solenoid once I am up to speed. Sounds like there is an opportunity for disaster in that scenario if I forget to disengage it.
I attach a picture of the outside of the cover. I may have an extra cover, but I don't think the adjustment screw would already be pre-set.
I replaced the screw with the old one and added a nut to spin down and secure the wire, but I do not have a sense for the initial gap.
I do have a lift, so I believe I could have someone run the car up to about 20 MPH and I could screw in the adjuster until I get engagement. Sounds kind of nerve racking to me, but it might be the only way to get the adjustment close.
One thing I noted today. When I ground the OD at the governor, I get the solenoid triggering when the key is OFF as well as when it is ON. Shouldn't this only work when the key is in the ON position?
Ross - I think the screw is the issue. Although it looks, from the outside, like the screw would not adjust the points, I took the cover off and can see that the screw does directly adjust the top point of the set. When I first got the car, the OD did not work and the Packard guys at Custom Auto in So Cal made it work. Maybe this was a fix they made?
HH - Thanks for all the info. The inside of my cover is a little different, but I can see how the points engage.
I traced the wires by disconnecting all the wires at the solenoid and at the relay, and then simply checking continuity. This is about as sophisticated as I get with auto electrics. But I do think it was a clean test, since I disconnected everything.
When I accidentally grounded the governor, the dash light was on and brite. It has always worked in the past. Once I put everything back (but with incorrect point gap) the light does not go on and the solenoid does not attempt tp engage, at least, I can't hear it do anything.
