Thanks Loren.
There was about a third of a turn of play before, and when the wheel was turned hard all the way to one side, it jumped the pulley. When I reattached the cable, I noticed that there was a lot of play in the cable, so I adjusted the turnbuckle until it was maxed out.( the cable still wasn't tight by any means) I then went topside to check the wheel, there was no play, but I could hear kind of an abrasive sound when the wheel moved, and then it jumped the pulley again.
Based on what you've told me, I'd say I tightened it too much. I'll keep playing with it.
thanks,
Brett Contreras
