Battery/volts charging question

[tw322]

Drove my Bronco to yesterday and noticed my volt meter showed it was only charging at 10. Went to start it this morning after my shift and battery is dead. Jumped it and drove home and volt meter showed it only nchsrging at 8. Now this may be a stupid question but does this sound like the alternator is not charging or the battery is just getting old?

Alternator regulator is bad or your belt is loose.

If the alternator is charging properly you should see 13V on a voltmeter...at least....after its been running for a few minutes after starting it.

12.5 -12.6 is a fully-charged good battery voltage with the engine not running...anything less than 12V is problematic and anything less than 11.5 is a nearly dead battery. Your is/was beyond dead.;D

12.60 v = 100%
12.35 v = 75%
12.10 v = 50%
11.95 v = 25%
11.70 v = 0%

Perfect thanks guys. I kind of figured it was one of these but just needed the doctor's second opinion. Looks like I will be wrenching on it soon. And the belt thing is damn funny! Thanks again.
