CAT 289C won't crank

I just bought a 2012 289C XPS high flow machine. Picked it up in western MI then trailered it to Central NY. I went to unload it at the shop and couldn't get it to start. When I turned the key on, the glow plugs turn on, lap bar switch engaged, park brake on, and still nothing happens when you turn the key to start. No clicks or buzzing. Even when the lights are on and you turn the key you can't see the lights dim or anything. I believe I hear the fuel pump run every time the key is turned on, but nothing after that. I am going to try to investigate electrical connections and test the starter. I just don't want to beat my head against the the wall for nothing. If anyone has any ideas it would be greatly appreciated.

Thanks
