Difficult to tell from your description... First thing I would do is go into the engine compartment and unbolt the ground connections and sandpaper the paint off , put grease on the connections and tighten the nuts...
Next, I would go to the battery set, sand and grease every cable connection and reinstall..
While you have the straps off the batteries freeing up the vent caps, pull them off and water the batteries... Also use the no voltage moment to check the nuts on the battery selector switches for being tight... Being a nutcase about low ohm battery connections I would also pull these off, polish, grease, and reinstall...
Then do a good equalizing charge on the battery set and see how it goes...
