Buyers salter control box
I have a used Buyers spreader control box that came with my plow truck. Unfortunately, only the light comes on. I wanted to use it to control my TGS05. I'm positive everything is wired and grounded correctly, as I can bypass the control box and the spreader motor works beautifully, albeit at full speed. So I picked up another used Buyers control box from the local dealer that he got on a trade in. That box turns on, but will only Blast the motor.No speed control. The rheostat doesn't seem to work. I by passed the fuse in each box so I know it's not that.
So I figure the circuit board or rheostat is toast in both boxes. Is there a source for replacement parts for these boxes that anyone knows of?
And if I can't rebuild the boxes, is there any reason I couldn't just make my own setup via an inline fuse, toggle switch, and heavy duty rheostat for a speed control? I wouldn't have a blast function but that's no worry. I suspect that someone may have installed power to these boxes w/o grounding them properly in the past.
Any comments would be welcome.
