    ALWAYS discharge the high-voltage capacitor first if you even think your hands will come close to any HIGH VOLTAGE components.

    Jeff mentions this: Anything in the high voltage ( magnetron, capacitor, diode, wires to and from ):
    ...Use a metal ( not the shiny chrome type ) screw driver with a insulated handle to short across ( touch both at the same time ) the terminals of the high voltage capacitor to discharge it.

FIXED JVM3160RF2SS GE Microwave - PCB Relay Wiring

Greetings everyone, new here. I hope you are staying safe.
I'm reassembling a JVM3160RF2SS, which keeps blowing the fuse. One of the interlock switches was misaligned. I put everything back together except the PCB. There is a connector with black and white wires that connects to a relay with the 2 prongs on the board. It's circled in the attached image. I'm not sure which way it should be connected and don't know if the relay is polarized. Does anyone know or have a similar board that they can compare to. While I'm searching for the wiring diagram and images, I thought I'd ask here.
Any help would be appreciated, thank you!

Doesn't matter. If it did there would be different size terminals. On AC components it doesn't matter which side is L1 and which side is N. The Alternating Current means that 60 times a second the voltage goes between +120V and -120V. Switch the wires and it's still going between +120V and -120V 60 times a second.
