So my pump died and I don't know if it was running on 115 or 230? It's on a double breaker, which suggests 230, but the wires are black, white and green, which suggests 115.... The old pump wiring diagram, if I'm reading it correctly looks like it was wired for 230 (high voltage).
I want to make sure with a volt meter but I don't know how- do I touch both black and white wires with a multimeter to check the voltage, or black to ground? Or....?
