    Okay, so I went to test my equipment and my salt spreader controller out. Nothing from the salter and no indication from the controller, so I tested the leads in , which there was power. I pulled the cover off, and noticed a piece that looks burnt, so I might just go to an electronics repair shop and see if they can just replace it.

    All that aside, I want to make some backup boxes, in case I run into issues mid-season. I am running a Western pro-flo tailgate spreader. I do like the option of different speeds, but do not want to mess with the more expensive rheostat option. I have seen posted about using a box, simple switch for on/off, a relay and a 3-way for 3 speeds using resistors. My question is what are some good resistors to do the trick (and resistance rating) to get a low, medium and obviously no resistance for full speed.

    Also, if anybody knows what the red and white connectors on the Western salt spreader controller are called, I would like to match them so the boxes are interchangeable.

    If you have any pictures of suggestions, lets see/hear them
