On a 1947 M-5 with o/d and a 12 volt conversion, the overdrive relay buzzes or clicks continually until you lift your foot to let the o/d shift, but only clicks when the o/d dis-engages. Is the relay seviceable or can it be cleaned, or does it need to be repalced? Can it be another problem??

Hmm. OD, relay, 12 volt. Something extra here. Granted this is a conversion, but the relay should burn out with 12 volts to it, ditto the solenoid. Eliminate the relay, (12 volt systems did not have a relay) put in a 12 volt solenoid, and do some jury rigging, having studied a 12 volt wiring diagram.

Tom - 56 & 57 12 volt Od systems DID use a relay. In 58 they did away with the relay and incorporated the relay's function into the solenoid. That non-relay solenoid IS different than the 56-57 units.;)

Thanks Bob, I'll file that away. Would it affect a changeover to 12 volts? Could you just replace the relay and solenoid and keep on ODing?

Anne, good link. I've lived on those pages and not seen that. Looks like it would be ideal for a new installation.

The 6V relay for a very short time is making it's own ground. hence the buzzing. As soon as it thinks a ground is there, then it's not. Hope this not as confusing as it sounds. A horn relay, horns and starter is about all that will hold up to 12 volts, and if it's hard to start, then the starter will burn up. Those items don't have 12V often.

Will a 6V clock on 12V make the day go faster???

Yes.;)

No, but it'll shorten it's lifespan for sure![:0]

Thanks for all the input on this relay issue! I believe its a 12v relay-will try and clean it up or replace it.
