That's surprising - unless the ceramic is very damaged indeed OR unless the gold-plated wiper arms are bent, distorted or otherwise not making proper contact.

The ASA ceramic disc-track can be found under the ASA Dial.
You could see it by removing the ASA dial - without removing the camera top-plate ... but to check it out with a multimeter and to attend to possible wiper mistracking you would have to remove the camera top-plate.

That adjusting the ASA has no effect upon your exposure readings pretty much confirms that the trouble-spot is indeed at that variable resistor.
