Grizzly NJ, first there wont be any votage comming out that wire you tested unless the engine is very hot when you test for votage as the regulator going into the enine block acts as a switch only activated by tempeture. If you tested while the engine is hot and still no current it could be that thermocople that is plugged into the engine has gone bad (although I have never heard of this).
Also, make sure you clean the radiator of all mud and debre that may be restricting the air flow to the radiator. Other than this I have no idea what it could be.
