The ground to the case is a good thing and should be there.
Check for a bad through body starter cable from the battery by disconnecting both ends and checking the ohms reading. Should be very low around an ohm or maybe 2.
You may have corrosion in the cable that is causing a voltage drop.
Likely at the battery terminal end.
