Just bought a couple used Aurora 45-ohm controllers. One works, the other cuts out around 3/4 to full throttle. Any advice for repair? Thx in advance.

Look to see if the wiper is moving away from the coil. When you get to the point where it cuts out, push the wiper in towards the coil with a toothpick or similar to see if you can re-establish contact. If that works, then the wiper is probably moving out of plane with the resistor coil. If you can dis-assemble the controller, try to bend the wiper in a little to compensate for the wear on the end. That might allow you to get a little more use out of it.

Good Luck!
