Back at it for an evening. Recieved a spark arrestor knob. Thank you very much @maymayday
First step, disassemble the provided switch. Four screws on the back. One more holding the red knob from the inside. Four major parts plus a spring. Do not loose that spring!
Next, spend an hour digging through my junk to find a scrap of solid core wire. Came up empty so just used some well sized stranded. Strip at least three cm.
Yeah that wire has to go out the other way. Drilled out a thin layer of plastic left from the print. Stuffed the wire through. Both wires installed.
Assembled. Added got glue to stabilize the wires and hold them in place. I also used a drill bit in my fingers to clear out the holes for the spring to save some frustration there.
Tested it with a multimeter. Reassembled the switch with my new knob. Hmmmm what’s wrong with this situation. Doh!
Disassembled switch again, reassembled with the mounting plate in place.
