My plow is dead again.The last time with the help of repoman I was able to get back up and running. I was able to get the plow to lift today, but very slowly, then it just stopped moving, I was able to drop it as well, now the motor is working but no movement. Checked all the connections and all were good. when it lifted it went really slow, and moved side to side extremely slow, then wouldn't move at all.Im going to get some dialectric grease and a wire brush and clean and grease all the connections,any other suggestions? Any help would be greatly appreciated. Also, if I were to use the plow to just push snow, (we have 12-20 ionches coming) even without it being able to move can I do any damage to the plow or my truck?
