I`ve noticed that my Charge indicator on my dash seldom gets much above 12volts, especially at lower speeds on my VP 5.0 l. The origional alternator was re-built a couple years ago. My batteries are newer, less than two years old and I keep them fully charged before going out each week. Is this a normal reading or perhaps is my guage off or perhaps the alternator not working like it should be for being "re-built". Any suggestions without getting into too many diagnostic tests.
