 GFL 10 Installation and Configuration Instructions
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 .
