What should the battery voltage be on a Honda Civic?
The meter should read ~12.6V when your key is first turned to AUX, then 13.8-14.5V after it starts. After the battery has been recharged sufficiently while driving, the meter will alternate between 12.8 and 14.5 or so volts. Anyone suspecting charging system issues should know what their battery voltage is doing.
