hey guys i ran across an older warn 6000lb. winch i went to look at it the guy said it worked. we hooked it up to a jumper box and nothing seemed to work. im not real sure we knew what we were doing but any way its an older model with a black knob to engage or disengage. he wants $100 for it as is i dont know if its worth it or not i definantly cannot afford a knew one can i rebuild this? whats the best and worst case sceniero. thanks
