With the engine ON and running over 1200RPM, you should have ~ 13.8 to 14.8 V=

With the engine OFF,  a good battery will read ~12.6 VDC

Check and fill the electrolyte level of you have removeable caps, then put t=

Could be the alternator itself or alternator regulator.

Newer cars =E2=80=93 some =E2=80=93 will drop the charging if the battery lo=

If the battery reads 11.33 v whether the car is running or not, that means e=
ither the battery or the charging system is bad, right?
