With the engine ON and running over 1200RPM, you should have ~ 13.8 to =
14.8 Volts Direct Current (VDC) reading on your meter across the battery =
terminals.

=20

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

=20

Check and fill the electrolyte level of you have removeable caps, then =
put the battery on an overnight charge, get it to ~12.5 VDC, then try =
again.  Most alternators are not rated to charge a dead or dying battery =
and sometimes you will toast the regulator if it is trying to charge a =
low or dead battery.

=20

Could be the alternator itself or alternator regulator.

=20

Newer cars =E2=80=93 some =E2=80=93 will drop the charging if the =
battery load exceeds the rating of the alternator, others will just =
attempt to supply whatever the current load is until they burn out =
something.  My Jaguar tells me both if the battery is low on start or if =
the charging system is not working after starting, the miracle of =
technology.

Cheers!

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