I agree that many, but certainly not all of the dash gauge issues stem from an inadequate ground under the dash. I have literally dozens of ground wires going to a single grounding post. My Newell does not seem to have a large ground wire running from the batteries up to the dash. The dash ground seems to rely on a ground to the frame. As soon as the temperatures cool down some, I plan on running an additional 6 gauge wire from the power panel in front of the passengers feet down to a different location on the frame and see if that helps. I would love to run a 00 gauge wire from the battery up to the front but that would be some SERIOUS effort.
