Jim Yergin Posted January 4, 2011 Report Posted January 4, 2011 My overdrive relay stopped working. I searched the web and came across this site with a fix using a $7.00 relay from Radio Shack. I built one and it seems to work. I thought I would pass along the information in case it can be of use to someone else. http://www.studebakerparts.com/studebakerparts/store/s/html/pages/relay.html Jim Yergin Quote
Young Ed Posted January 4, 2011 Report Posted January 4, 2011 Seems like a lot of work unless you are really determined to maintain the stock look. Dads 50 ply has been running a similar relay with the wiring hooked directly to it since the mid 90s. Quote
TodFitch Posted January 4, 2011 Report Posted January 4, 2011 Seems like a lot of work unless you are really determined to maintain the stock look. Dads 50 ply has been running a similar relay with the wiring hooked directly to it since the mid 90s. The write up was fairly long and detailed, but it distills down to this: 1. Remove cover and gut original relay. 2. Install modern relay on frame. 3. Re-install cover. That doesn't sound like a lot of work to me compared to all the other repair procedures on our old cars. For example, I've been putting off dealing with a oil leak at or near the crank seal on the chain case cover. If I'm lucky, for my car that is: 1. Remove hood. 2. Drain cooling system 3. Remove radiator shell and radiator 4. Support front of engine with floor jack 5. Un-bolt front motor mount from engine and frame 6. Jack front of engine up enough that the vibration damper/pulley clears frame 7. Remove vibration damper/pulley. 8. Remove chain case cover 9. Probably install Speedy-sleeve on crank 10. Install new seal in chain case cover 11. Reverse all of above installing new gasket. If I'm not lucky and able to get enough clearance to remove the vibration damper then I'll have to pull the motor. And on that car that means removing the engine and bell housing as an assembly with the bolt in frame cross member. And the bolt-in frame cross member is where the master cylinder mounts, so I'll need to flush and bleed the brakes too. Anyway, swapping out the guts of a relay case sounds pretty easy to me and would make the engine compartment look nicer. At least for those of us who like a vintage appearance. Quote

While I am happy to know that your dad found a substitute for the relay, that knowledge does not tell me what he used, where to get it, or how to connect it. The site I posted provides that information. Whether or not you choose to install it within an original relay box is irrelevant. I happen to like it that way but that was not why I posted the site. I just thought someone would like to know where to buy a substitute, what part number to use, and how to wire it up. Jim Yergin Quote
Young Ed Posted January 5, 2011 Report Posted January 5, 2011 I have stated many times that we used a 12v relay from a security system which works at 7.2volts. Did not intend to say you shouldn't have posted it. Quote
BobT-47P15 Posted January 5, 2011 Report Posted January 5, 2011 Good info Jim. I saved it for future reference. Quote
aero3113 Posted January 5, 2011 Report Posted January 5, 2011 I love mixing old with new,thats a great tip. Just wish I had a overdrive transmission . Quote
1941Rick Posted January 5, 2011 Report Posted January 5, 2011 Use a "Bosch" style relay......good for 30 amps and the wiring schematic is on the relay. They are small and can be hidden very easily. Quote
fedoragent Posted January 6, 2012 Report Posted January 6, 2012 Use a "Bosch" style relay......good for 30 amps and the wiring schematic is on the relay.They are small and can be hidden very easily. Does anyone know where one can get the Bosch style relay? Thanks, Jon Quote
Plymouthy Adams Posted January 6, 2012 Report Posted January 6, 2012 these and the associated pigtail can be picked up at any of the auto parts places..often on the help shelf..or a quick trip to the the junkyard along with a set of dykes and snip one out of a harness.. Quote
Dodgeb4ya Posted January 6, 2012 Report Posted January 6, 2012 (edited) If you have a volt/ohm meter and know how to use one you can test your relay on or off the car with the relay schematic. Othwerwise lots of times a relay fails because of dirty contacts. Just carefully pop the cover off and carefully clean the contacts and try it again on the car. You might just get lucky and the OD engages once again! Here's a quickie simple test... Bob Edited January 6, 2012 by Dodgeb4ya Quote
