If the guage wasn't doing anything goofy before the new batteries, it wouldn't hurt to check that alternator but more importantly, look closely at the heavy wire that bolts on the back of it. On mine the cable rotted off the connector end but didn't find it until I went to change alt's. Wasn't about to return the new one cause I didn't know how good the old one was and hate it when that crap fails on the road. My guage went a bit goofy too prior to that. Must have been increases/decreases in the connectivity of the cable to the cable end.

Check the plug on the top rear of the alt. Sometimes the heater hose bracket gets bent down and puts pressure on the wires in the plug, make sure the contacts are clean.
