@gunrunnerjohn posted:Not sure where you're installing the resistor, but putting it across the contact would provide a leakage current, that probably wouldn't be good.
I was thinking a resistor in series with the diode to make up for the lack of resistance in the silicon diode (when compared to the original disc, or would this actually increase arcing due to more load?). But I did not mean for my resistor comment to overshadow the clarifying ask with regards to TVS theory and placement within the whistle control circuitry.
