Troubleshooting the Gauge Type

When connected to a gauge, the GFL 10 adapter gauge type is set to Auto Detect by default, and the adapter automatically detects the type of gauge it is connected to. If the fluid-level reading on a connected Garmin chartplotter or marine instrument changes with the engine RPM, the adapter may be detecting the wrong type of gauge.

NOTE: The fuel level changes when the boat is moving. Test the gauge-type setting when the boat is not moving.

To test the gauge-type setting:

1.When the boat is not moving, put the engine in neutral.

2.Use the throttle to increase the engine RPM. If the fluid-level reading changes with the engine RPM, change the gauge type.

To change the gauge type:

1.From the NMEA 2000 Devices list, select the GFL 10 device.

2.Select an option:

•For most Garmin chartplotters, select Review > Gauge Type.

•For other Garmin marine devices, select Config > Gauge Type.

3.Select an option:

•To automatically detect the gauge type, select Auto Detect.

•To indicate a one-coil gauge, select 1 Coil.

•To indicate a two-coil gauge, select 2 Coil.

4.Perform the gauge-type setting test.

Resetting the Fluid Level Calibration

You can reset the fluid-level calibration of the tank that the GFL 10 adapter is associated with.

1.From the NMEA 2000 Devices list, select the GFL 10 device.

2.Select an option:

•For most Garmin chartplotters, select Review > Level Calibration.

•For other Garmin marine devices, select Config > Level Calibration.

3.Select Reset Calibration.

4.Select Yes.

5.Calibrate the fluid level.
