I just replaced the alternator on my 6x4 diesel gator because i wasn't getting more that 11 volts from the battery with it running. I charged the battery and put on the new alternator. I now get 12.5 volts before starting and after it starts with no increased voltage when the engine is revved up. The belt is tight. Also I now have the battery warning light coming on in the dash. The lights and other electrical all work but as expected there is a drop in voltage when the are switched on. Do I need a new regulator? Any other ideas?

Did you have the old alternator tested to prove it was bad? Could be wiring issue elsewhere.
