Nw Iowa | Thanks, to previous poster, it does read mph. I think my old 300 box is also getting a bit tired. All that wiring to the power module gets kind of bunched up in the cab, wondering if there isn’t some pressure on some of connector wires, but ever since I put on new harness, it has been erratic, work okay for a round or two or even a couple of hrs and than a row will quit reading. I will try the ohm meter. Maybe just a poor harness | |
