News — Bad Alternator
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....
