NOTE:
Power out - The control box supplies power to the winch motor terminal F1 and connects winch motor terminal F2 to terminal A(Armature)
NOTE:
Power in - The control box supplies power to the winch motor terminal F2 and connects winch motor terminal F1 to terminal A(Armature)
1 Refer to the winch circuit diagrams For additional information, refer to Winch Winch - Description
2 Using a multimeter, monitor terminals F1, F2
