Just an aside, when I purchased my Langdon HEI Tom said he was out of core dizzys and didn’t know if he would get more, his words: “i worked from east coast to west and am running out”….
If you go to his website since then it now says sold out…….
As to the relay… I did it because I was chasing a problem, and the quality of my ignition switch is unknown (I don’t have a stomp starter so my ign switch is not stock to my 46).
In my case I would much rather have to jump the (plug & play) relay than attempt to jump at the ignition switch or Hotwire the coil.
