HONEYWELL GAS VALVE VS8540E 7019 VALVE QUESTION

[ernie]

I have this new old stock valve. What I don't understand is why there is a black wire going from the thermocouple port on the bottom to the TPTH terminal.
If the valve needs a thermocouple from the pilot assembly, can i just remove the wire and connect a thermocouple to either the bottom or side port?
can anyone answer why the black wire is on in the first place? Lucky I have both NG and LP conversion caps

Because it doesn't need a thermocouple. It is exactly what it looks like. There are lots of older inserts that proved the pilot flame with the thermopile. Lots of new decorative log sets are still like this.

SO, if I think about it, if you needed the thermocouple and your pilot has both the thermocouple and thermopile, i could take that jumper off and replace it with a thermocouple? I would assume just unscrew it from the bottom and cut the wire that is soldered to the tab terminal and it would work? This valve has two places that you can screw in a thermocouple.

Is there an electrical connector in either of the places that the thermocouple can thread into?

Like I said before..not all millivolt valves use thermocouples. I'm not sure what you are trying to fix or what other posters are saying to you.
