Thanks, Craig. It’s a weird application. It’s a capacitor that’s used to run the pulse pump on my 1960s Italian Omre brand espresso machine. These machines used either rotary pumps or pulse pumps. Mine has a pulse pump and I’m almost sure the way this capacitor is wired into the pump that it’s what provides the “pulsing” for the pump.
I can look at it more closely and give you the exact location of it relative to the circuit in a little bit.
