Not really, there should be a Red wire from the B post on the alternator to the rear right stud in the fuse panel. Then across the buss bar to the left rear stud. The 10 gage Red wire from that stud goes to the L+ side of the ammeter, the a Red/White wire goes from the B+ side of the ammeter to the front left stud, across the buss bar to the front right stud and a 10 gage Red/White goes to the battery connection on the starter solenoid. That's how the battery gets charged and the ammeter indicates total charge and discharge of the entire electrical system. Now the two things that would cause the alternator not to charge, normally, is a burned out ammeter lite, or the alternator is not grounded to the engine, the engine is not grounded to the frame, or the battery ground is not making a good connection. HTH.
