I was getting a short fault and an overload fault with my Prodigy controller on our way back from the Fall Rally. I found a bad magnet coil with my multimeter, so I just cut and capped off the wires on that one wheel for the rest of the trip home. We were traveling through a lot of heavy rain at the time, and I think that the magnet windings got wet somehow and went bad. The brakes and controller worked flawlessly after I isolated that one wheel. Although I only had three working brakes for the rest of the way home, it was much better than having the intermittent and unpredictable stopping power that was occurring with the bad magnet in the loop.
Now that it has had a chance to dry out, I will test it for the proper resistance. If it reads good, I might try to seal it with some potting epoxy and put it back into service until I install the Dexter Nev-R-Adjust brakes that I have waiting in the wings for when my original brakes are used up.
