One of our trucks has a brand new (new at beginning of this season) electric western striker salter. Worked flawlessly and have been very happy with these. Today after some salting the spinner remained on and on full speed even with the controller off. Played around with it all a few times and still the same result. The only way for the spinner to be turned off is to unplug the connector at the back of the truck/back of the salter. The controller can turn on and function as usual and turns the conveyor on and off but the spinner remains constant on no matter what unless its unplugged. If you do unplug it, the controller beeps signalling that it is disconnected like it should and of course then the controller needs to be unplugged as well so it stops beeping. We're thinking if it were say a bad ground, the entire unit would either completely function or not, not just the spinner part. Connections are in perfect shape so not corrosion. All connections and terminals on the module seem tight and in good shape, same as everything under the hood and battery. Any suggestions? With another storm coming tomorrow we aren't going to mess with it, just leave it unplugged until its needed. Not ideal but better than nothing.
