Winch test without a switch or relay??

[slats_bigbear]

So I have this old winch mounted on my Big Bear, its got 2 wires coming out of it, best I can figure out 1 ground and 1 power which would then go to a relay (I cant find a free spool lever/button/clip). Anyone have any ideas on how I can test it in both directions (reversing the polarity which would normaly be done at the relay so it will spin the opposite way) or at least one direction. Im hesitant to spend $50-60 on eBay for a relay and switch just to test it out and see if it works, and then have a big headache trying to return a open used electrical item. Thanks

Maybe each lead is a direction and mounting the unit to a metal frame grounds it out? real strange there is no freespool lever

free spool is on the right side of the winch facing the front of bike. if its a warn, it has the black bottle cap (but bigger) knob that will release, turn and lock. might be real hard to turn now, but once free, should be ok.

the 2 wires are the ground and positive leads as far as i can remember, and im sure if you hook it up direct to a battery it will turn ...
