Do you mean, power between the black and ground but not between the black and white? I assume you mean at the microwave receptacle and not literally "at the microwave", which wouldn't eliminate the microwave cord itself.
Assuming you mean at the receptacle, this doesn't definitely mean the wire itself is bad, it could mean that the white wire connection at the other end is bad or something is bad upstream from it. To be sure, you need to test all along the pathway, wherever there's a connection.
You still haven't identified the year and exact model so we can take a look at the applicable wiring diagrams for the details.
As an example, I took a look at the diagrams for the 2006 40' Vectras (S40KD and S40FD) and see that the microwave's receptacle is wired to the inverter and there are two connections between it and the microwave receptacle. In addition to the two connections, the diagram for the S40KD shows a "blank receptacle" also in the line.
Here's the link to the 2006 S40KD diagram. You can see the connections, along with their locations in the middle of the diagram, the microwave is connected to inverter breaker labeled BLK:

Once you ID your exact year and model's diagram and determine its specifics. You'll need to check for continuity all along the path at each connection site or inline receptacle.
Here's the link to all the diagrams:
