Diesel Bombers - The Dodge Blues.

Well lastnight I went to o'reillys to get my batteries tested.The guy came out there tested them and they were both bad. He asked me to crank my truck so he could test the alternator.I turn the key and got nothing.Figured out the starter was bad,the two bottom bolt where beyond loose and has been bouncing around for who knows how long.So I put a screwdriver on it and got it cranked,but know my windows,speedo,a/c and heater blower,water temp gauge all do not work. I checked the only fuse for the windows and changed it and still nothing. Any advice would help!Thanks
