Ariens sierra 1440G belt configuration

Question

I recently pulled my cutting deck off to clean it. I went to put it all back together and I think I have put the belt on the wrong way because the blades wont spin anymore when they are engaged, the pully just spins becuase the belt is too loose.Is there somewhere I can get a diagram of how the belt is set out or is there something that I need to tighten in order to get friction on the belt/pulley
