Very likely. If you do find such a leakage path, before tearing the rotor 
apart check the inside of the connector at the rotor end. I had a similar 
issue several years ago with insect trash providing leakage between the 
connector pins when humidity was high. The pot seemed normal, but from the 
shack end of the cable I measured leakage (~850 ohms) between one of the the 
motor leads and the top of the pot.

Cleaning inside the connector shell, backfilling with plain old vaseline and 
sealing around the (useless) rubber boot solved the problem and has 
prevented a recurrence.
