The SEMTECH-DS Mobile Emissions Analyzer is all strapped in and all of the other wiring has been connected and tested. This unit requires the use of a deep cycle battery to power it. We chose the Optima Yellow Top which performed like a champ. We had to place the testing equipment in the passenger seat area because that was the only space available that size. We had to remove the door to get it through the window, but that allowed us to work on the exhaust and run the various wires too. Fortunately, the cushioned base of the unit fit perfectly onto two of the rollcage bars beside Dalton. We just had to use hose clamps to strap it to the tubing. Then we ran two ratchet straps around the front to back sides and one side to side. We placed rubber tool box matting between the unit and the base to further cushion it and to prevent it from sliding. It worked as planned and we saw only slight movement during our runs throughout the test.
