Question about 2005 Ford Explorer
I don't know where you checked alternator out-put? I'd check at the alternator bat terminal and across battery posts, both, the reading should be close to the same.
It's possible when you took battery cable loose to install ammeter in series, a module may have shut off? Use a jumper wire to keep connection till you get the ammeter hooked up. Just my opinion.

Possible loose or worn alternator belt. Check the condition of the belt. If it's worn, replace it. If it's just loose, tighten it up.

SOURCE: Low voltage
what is the condition of the battery cables you are probably onto something about a ground but i dont think your ground issue is going to be at the batteries you may not have a good ground on the alternator. The next thing I would check is ... the alternator itself do you know that you are getting between 13.6 and 14.2 volts out of the alternator, a under charge or a overcharge condition both are bad for batteries.
I would check alternator output first if it is not within the above range you need to replace it
If the alternator is putting out in the range of 13.6 to 14.2 then you need to look elsewhere... you may have something draing the batteries overtime interior lights, electric brake controller for trailor brakes if equipped sound system if anything is getting power without going through a switched circuit this could also be your cause.
hope this helps

Testimonial: "Thanks a bunch ithink it needs a high idle "
SOURCE: red battery light on dash
Charging is sufficient you want 2 volts above battery, for that dash to be on there will be a terminal on the alternator that is not connected it is a single wire you will need to make sure that it is connected,the terminal have tendency to break off and sometimes people who put the alternator on forget to put that terminal on they just dont see it it a wire by itself
