9. Solució De Problemes

• Gauge Not Powering On:
  • 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 gamma.
• 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.
• La llum de fons no funciona:
  • 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.
