Hi, im new here. I was plowing this morning, 0°farenheit, and in the middle of a driveway the plow wouldn't raise. Lifted it with a heavy duty strap to get ot home. Tightened the battery ground, put some dielectric grease on main power plug and it worked again, but with plow lights on, controller sometimes strobed on and off instead of working. While plowing my shop lot, headlights cut out, then a miuite later complete plow power loss. Jumping the selonoid fires up the pump. Any ideas would be appreciated
