Solid state winch control

Posted on Feb 6, 2014

I am interested in building a solid state control for my Warn 8274 self recovery winch. The current control scheme uses 4 constant duty 200 amp solenoids. 2 switched in parallel to connect the field 1 terminal on the motor to the armature for power in, and the other two in parallel to connect field 2 to the armature for power out. The solenoids are quite expensive, and during prolonged use, will occasionally weld themselves closed, and require replacement
