Tommy is correct .... The knob needs to have pressure on it and try to turn the spool in one direction or the other.
Also, one can touch / flip the switch quicly, just to make it make contact for a second or two, while one tries to " engage " the lever .... There is nothing wrong with the winch, it is just between gears / sleve ,if you know what I am trying to say. The " engager " is sitting on top of a gear, that is all that is wrong with it >
If the motor is running in either direction, it is just need to be engaged !!! You will feel it when it falls into place ...
OR, YOU CAN BUY YOU ANOTHER, AND I WILL TAKE THAT JUNKY, NO GOOD WINCH, THAT IS ON YOUR MACHINE NOW .....
