I have a antique elect. tulsa winch that hasnt been used in 10 yrs. It worked fine before it was set aside and hidden under some junk. Its been exposed to to the elements the whole time. The winch is rated at 10k#. I think itll make a fine winch for the rear of my rig as I already have a warn 12k in the front. Whats the best way to get this old thing back in working condition? When I apply power all it does it 'click'. Should I rebuild the motor?
