I am having a fit here guys... '53 Stude overdrive relay. The repops are not wired internally like the original. There are four terminals on the authentic piece. As far as I can determine, one terminal is "hot" all the time. Anther "hot" when the ignition is on. One more "hot" when the key is tuned and yet the last one hot when the governor reaches a certain speed. the question: Does anyone know for certain how these are wired and / or work? thanks much!
The internet is your friend... Give this a try. https://www.studebakerparts.com/studebakerparts/store/s/agora.cgi?page=wirediagrams.html Mike
Thanks... good advice. The only problem is the wiring diagram does not match the car. And yes, the car is a true survivor --- never played with. I have looked at three diagrams and not one matches the other???
Studes used basically the same Borg Warner OD as Fords/Linc/Mercs/Chevys did. Do a search here (and on the 'net) and you'll certainly find wiring diagrams. The relay terminals should be as follows: 1. Power (which comes from the ignition coil, or at least from a source having the key turned on) 2. Solenoid (power out to the solenoid when the governor triggers the relay) 3. Governor (acts as a trigger for the relay). I don't know why you'd have (or need) a fourth terminal, unless Studebaker had the relay act as part of the kickdown mechanism. Fords had the solenoid wire pass through the kickdown switch on its way to the solenoid. Have a look here for a cool replacement: http://www.studebakerparts.com/studebakerparts/store/s/html/pages/relay.html
