    Why is my Trackunit GPS counting operating hours when the machine is off?

      Deborah WilsonAug 4, 2025
      This may be happening because the main breaker is on the negative wire (ground wire from the machine battery). When off, the inputs may register a voltage level and start counting operating hours. To avoid this situation, connect the digital input 4 (pink wire) to the chassis/ground on the machine.
