Microwave motor replacement help.
Today I received a replacement motor for the microwave.
There are no positive or negative marks on the terminals. I'm not sure if it even matters on a synchronous motor. Can someone please take a look at the following links and if possible advise which is which?
The microwave has a red and a black wire that attaches to it.

A single phase synchronous motor is AC so polarity of connections won't matter. All it typically is for a small sync motor is a wound stator winding with a permanent magnet rotor and a 'detent' on the rotor to ensure it runs in the desired direction (can start in either direction if it's a single phase unit without a detent).
Thanks Skepticist. Put back together and working now.
