9. Riešenie problémov

  • Meradlo sa nezapína:
    • Check the red wire connection to the 9-32VDC power supply.
    • Verify the black wire connection to ground.
    • Ensure the power source is active and within the specified voltage rozsah.
  • RPM Reading Incorrect or Stuck:
    • Re-check the blue wire connection to the RPM signal input. Ensure it is securely connected and receiving a signal.
    • Verify the speed ratio setting (refer to Section 6). An incorrect speed ratio is a common cause for inaccurate RPM readings. Adjust the speed ratio according to your engine's cylinder count or outboard poles.
    • If the gauge is stuck at maximum RPM, it often indicates an incorrect speed ratio setting or an issue with the signal input. Try adjusting the speed ratio.
  • Nefunguje podsvietenie:
    • Check the yellow wire connection to the backlight power supply.
    • Ensure the color change button on the backside of the gauge is functioning.
  • Hour Meter Not Recording:
    • The hour meter operates when the gauge is powered. If the gauge is on but the hour meter is not advancing, ensure the RPM signal is being received correctly.
