Is it the Battery, Alternator, or Voltage Regulator?
It could be any one of the three, or an undetected voltage drain caused by a trunk light, under hood light, or glove box light that does not go out when the lid is closed. An alternator is based on the rotation of a magnet inside a fixed-loop conductor. The output circuit and the field circuit make up the automotive charging system. The first thing that should be checked is the battery state of charge. If it has a built-in hydrometer (charge indicator), a green dot means the battery is 65% to 75% charged and okay for use or further testing. If the charge indicator is dark, the battery is less than 65% charged and needs to be recharged and load tested. On 1985 and later model Chrysler vehicles, the charge indicator on some batteries also contains a red dot which shows if the battery is less than 50% charged. If the charge indicator is clear or yellow, the level of electrolyte inside the battery has dropped too far to give a reading. It also means the battery will need to be replaced soo
