Thanks for the help guys. Great suggestion by Roy.
I checked and I’m not seeing 9V on either side of the switch. Hmmmmmm. So I guess something is going on with the DC jack??? I’ll try desoldering that from the board and see if there’s a glob of solder or something like that on the underside that’s shorting it out. I’m not really sure what else it could be.
I might be better off to just buy another port and try again. Does anyone know the Mouser part# for this port?
