Struthers-Dunn relay replacement

I opened a ticket a month ago but haven't got a reply yet so I figured I might find someone with an answer on the forums.


The relay on my 2022 Advanced Series 48A station is stuck, after investigation it is a Struthers-Dunn relay inside. I will try to clean up the contacts, but I am planning to replace the relay. Looking at the forums it seems that the best replacement would be a Packard relay.

  1. Is there a procedure on the replacement?
  2. Looking at the guides it looks like the wire connectors for the relay will need to be changed, where can I find the specs or part numbers for the replacement connectors?
  3. It is also not clear whether the existing holes on the metal backplate will be compatible or if new ones will need to be drilled.

Thank you in advance for your help.

There is not a formal procedure.


The parts you would need would be:


Relay with harness

Wire Ferrules

Most kits have holes for both pre-drilled.
