Having not seen the actual motor, I can't be sure - but the 240v~ motors I've worked on havent had internal ground connections. 240v~ motors don't require a ground to work. Two 'hot' legs and a neutral are all that's usually required. The "T" leads usually connect among themselves to determine operating voltage and direction of rotation, and there are (usually) "L" leads that connect to the power.
Often, there's a wiring diagram that's printed on the underside of the wiring cover plate, or otherwise on the motor's nameplate. The connections are generally pretty simple and someone who's worked with motors could likely have it up and running in a couple minutes.
Frank: Can you take pictures of both the wiring box (and its cover) and the motor's nameplate. That might help us determine something. Otherwise, take your motor and switch to an electrical repair shop and ask them to wire it for you. It'll only take them a few minutes, and likely won't cost you very much at all. After all, what's your time and frustration been worth so far?
