What to do if the Yamaha E40GMH gauge display does not wake up?
If the gauge display doesn't wake up, it could be due to a lack of electrical power or a damaged gauge. Try these steps: replace the fuse, securely connect the couplers, replace any damaged wires or hubs, or, if necessary, replace the gauge itself.
Why Yamaha Outboard Motor illumination does not light?
If the illumination does not light, it could be due to a lack of electrical power or a damaged gauge. You should try replacing the fuse, connecting the couplers securely, replacing the damaged wire or hub, or replacing the gauge.
How to fix Yamaha Outboard Motor tachometer showing incorrect engine RPM?
If the tachometer shows an incorrect engine RPM, the engine recognition might be wrong (especially for multi-applications). To correct this, push the 'SET' button for 10 seconds to default the engine number, then memorize each engine number again.
What causes Yamaha E40GMH fuel management gauge to show incorrect remaining fuel?
If the fuel management gauge shows incorrect remaining fuel, the fuel capacity setting may be wrong (specifically for SQR Fuel mgt Gauge). Fill the tank with fuel, and set the correct fuel tank capacity.
What to do if Yamaha E40GMH Outboard Motor gauge shows “----”?
If the gauge displays '----', it indicates that the digital signal is not being received. Check that the couplers are securely connected and replace any damaged bus wires or hubs.
What to do if my Yamaha E40GMH Outboard Motor speedometer shows the incorrect fuel level?
If the speedometer shows an incorrect fuel level, the fuel sensor selection is likely wrong. You should set up the fuel sensor to the correct resistance.
What to do if my Yamaha Outboard Motor gauge display does not wake up?
If the gauge display doesn't wake up, it could be due to a lack of electrical power or a damaged gauge. Try these steps: replace the fuse, securely connect the couplers, replace any damaged wires or hubs, or replace the gauge itself.
Why Yamaha Outboard Motor boat speed and/or coolant pressure gauge does not show?
If the boat speed and/or coolant pressure gauge does not show, it is likely that the optional sensor has not been installed. Install the optional sensor.
What causes Yamaha Outboard Motor gauge response to be poor or down?
If the gauge response is poor or down, a market obtainable unit connected to the system may have failed, or the signal volume has exceeded 50% of the capacity. Try replacing the unit or removing the heavy signal output unit.
