Electrical: 6 volt transmission relay connector

[Al Kurz]

All. I'm repairing up my '39 Coupe Express and one item I am missing is the cable that goes from the battery to the Transmission OD Solenoid. This 6 volt Solenoid has a tubular power connector, that holds the fuse, almost like a spark plug female connector. The Solenoid get's its power directly from the battery. So my question is, how do I connect my power to the solenoid as this connector is not a typical screw ring or spade type? Is there a special special something special? Thanks Al K

This looks like a Relay, not a Solenoid, the Solenoid on the Trans. would probably connect to the Kickdown Switch.
But that relay appears to have a Terminal that is already twisted and locked into it's receptacle and looks hollow so you could insert a wire and crimp it down, NO ?

Power could come from the Starter Solenoid Batt. Terminal.

Do you have the 1939 Overdrive Wiring Diagram ?

OR... maybe this Prewar Stude. is just too old for me to know.

You know, that relay looks familiar. I don't know if I have one in my stash of parts, or whether I saw one elsewhere, but that terminal stud looks like I have seen before. You know that bayonet socket looks like it might mate up with one half of certain types of inline fuse holders. Put a fuse on the long half of the matching fuse holder (the long half having the male bayonet pins), and click it into the socket. Just might work. I will check my relay stash tomorrow, and see if I can find one.

Whoa. That brass cylinder is the fuse holder. Give it a little twist and a tug and it comes right out. There should be a normal glass fuse inside--20 amp if I recall. The wire from your battery merely connects to the screw that is right next to it. And yes it is a relay. The solenoid is on the side of the transmission. In that era the solenoid does not engage the overdrive: that happens by centrifugal weights inside the unit. The relay and solenoid only operate to cause kickdown when you floor it.

Ok guys. You are correct. I don't know why I labeled it a solenoid when it is a relay. Wetware malfunction on my side. After your responses Ross and Gordr and StudeRich I see the power goes into the screw, then up the holder, then down the insulated holder and out the bottom. Problem solved so thanks for getting me rethinking the obvious!
