My Alternator is only Charging 10.7 Volts? Is my Voltage Regulator Bad?
Posted by CHRISTIAN CAUDLE on
Alternators can not charge at 10, 10.2, 10.7, 9, etc. Volts.... First, When a voltage regulator fails the battery light or gauge will come on indicating a charging issue. Continued driving will discharge the battery and is not good for overall battery life and condition. If you tested the system showing a reading of 10.7 Volts (or other reading lower than 12) then the testing is not done with a fully charged battery and not going to be an accurate charge system test. Even without an alternator installed on a vehicle running voltage will be 12 until battery is drained....
