Old ones didn't work right so I put new Polaris OEM hand warmer elements on. They still don't work right. They did get a little warm once but not enough to really make a difference. I tested the heaters a they both have 0 resistance. The thumb heater works fantastic. I checked the plugs and they are clean. The switch passes current in all settings. I even tried a extra heater I have laying around that I know works and it didn't get hot. What am I missing?
