Extra tips

  • Battery Check: Ensure your golf cart’s battery is in good condition. A weak battery can sometimes cause erratic gauge readings.
  • Firmware Update: If your golf cart has a digital dashboard, check for any firmware updates that might address this issue.
  • Professional Help: If you’re not comfortable with electrical work, it’s always wise to seek help from a professional mechanic.
  • Sensor Calibration: In some cases, recalibrating the fuel gauge sensor can resolve the issue without needing to replace parts.
  • Environmental Factors: Extreme temperatures can affect the gauge’s performance. Consider this if you’re in a very hot or cold climate.
