You can do this test to prove the bad ground. Put the positive test lead from your meter on the positive terminal of your battery and the negative test lead on the frame on a bare metal spot near the ground connection of your house battery and see what reading you get. reading for a fully charged battery should be 12.7. Compare that reading with the reading you get from testing Positive to negative right at the batteries. If your ground is bad the readings will be different between tests.
