Electrical Resistance of Minn Kota Armature

I'm using a multimeter to measure the electrical resistance of my Minn Kota's armature commutator. What I apply the negative and positive pointers to look like panels on that commutator. I've been checking one and another at 180 degrees from each other, and one and another side by side. The readout values I'm getting leap from about 13 to 26 to 49 to 193. So by what reading I've done on the process of determining whether the armature is any good, I'm inclined to believe wiring is burned out. Please let me know what you think about that. The Minn Kota, while we were on the water, had at first quit working, then worked again, and finally died altogether. I found that for the first time of the 11 years of using it, I had failed to take notice of braid line wrapped very tightly around the armature shaft and against the seal. The seal does seem OK, but I guess pressure on the armature shaft have extensively burned out wiring. What do you think?
