A slightly different repair to the usual but this builders hoist or winch had a problem in that the motor only worked in one direction.
A damaged PCB around a cut off switch that detects when the load has reached the top was causing the problem so it was repaired.
Also the up and down buttons on the end of the long remote cable weren’t soldered to the cable so that was repaired along with a small part of the cable where the outer insulation was leaving the internal wires exposed.
