How do I wire external power supply?

I think we’ve thoroughly hijacked this thread about wiring power supplies. Also, I believe there are so many items in this thread its getting hard for folks to get the full history of troubleshooting.

I’m closing this topic for now so we don’t spam folks with off topic stuff. If ya’ll want to start a new topic about issues, feel free though.

BTW it is totally fine to start a new topic and paste in a link (click the chain icon in a post you want to reference).
