I fell sort of silly spending time on a Polar Cub Type D, (espically ater reading about the dragon lamp/fan) but I'm doing this as a gift for a friend that loves these little 6" fans. The motor reads zero ohms and I suspect it's toast. Do these brushed AC/DC motors ohm the same as a regular AC motor? I'm testing the leads from the wires that go to the brushes. Or is there a different way to tell if the windings are still good?

Without a growler, you can do a simple test by placing ohmmeter leads on segments. A good one will increase in the ohms reading as you progress from the first two segments that are side by side to the the others, continuing all the way until you reach the first segment.
Hope this is clear.
The field windings will also need testing and should have some rather low ohms reading. Use the lowest ohms setting on your meter.
Cheers,
Bill

Thanks Bill.
I knew the process was different but couldn't remember how to do it.
