6V overdrive relay

I know, these are unobtanium. I saw a writeup about rebuilding one with a Radio Shack relay, but it's a 12V relay:

is there any reason one couldn't do the same thing with a 6v horn relay?


eBay has a "I want this" list you can get on. Maybe they have one for such things.

I expect that it is also used on many other ODs of the period. Maybe their $ites could help. Karl

Pat: Check with Randy Rundle at Fifth Avenue Antique Auto Parts in Clay Center, Kansas. He's a genius on this 6-volt stuff, and making alternatives work. He will soon be advising for SDC and will be introduced in the December Co-Operator.

Randy came to Omaha and sat in on Thursday's Co-Operator Tech Session, answering electrical questions. He arrived the night before and I was able to have dinner with him. GREAT guy, very knowledgable. A real asset for folks wanting to keep 6-volt cars alive and running on 6 volts. BP

I think the Bosch relay will work OK on 6 volts, but I'm willing to be corrected.

not the relay, IMHO. Check for oil on the governor contacts; that is a common cause of an otherwise good OD that just quits working.

I'll be sure to do that - my suspicions came from not finding the proper voltages on the relay contacts, though. I'll have to do the governor bypass to see what happens.

Did you check the Rube Goldberg switch that rides the curved metal piece.? The slide switch can sometimes not spring down and up at the proper rate, and if the contact is not made abruptly then the relay does not get activated.
