Measure the battery at rest, then measure across the posts with the alternator running. A fully charged battery without a surface charge should measure 12.6V. Measuring across the battery posts with engine running should measure 13.5-14.5 V.
If you have two batteries connected in parallel and only one is charging, you have a wiring problem or a bad battery.
Ok well I did measure before and after and it didn't change so being that it's a new battery I'm going with a wiring problem, more than like the culprit has to be the cable that connects the two batteries from negative posts, so I guess If I take the cable off and test for continuity I should be able to know if the cable is bad. unless there is another method I don't know about. Will it do any good to put the battery on a charger? I'm guessing not really since I need to find out what with the wiring, forgive me if I sound redundant but I'm beat and shouldn't even be replying to this, lol
