What to do if Yamaha 2CMH fuel management gauge shows incorrect fuel consumption?
If the fuel management gauge shows incorrect fuel consumption, the engine recognition might be wrong (especially for multi-applications). To fix this, default the engine number and turn the key switch on in order from the portside engine to re-memorize each engine number.
Why Yamaha 2CMH gauge operates unstably?
If the gauge operates unstably, it could be because a resistor is not connected to the ending hubs. Connect the gray 6-pin cap to the ending multi-hubs.
How to fix Yamaha 2CMH trim gauge showing incorrect position?
If the trim gauge shows an incorrect position, the initial position setting might be wrong, or the trim sender could be damaged. Put the motor in the fully trimmed-in position and reset the initial (zero) trim angle. If that doesn't work, replace the trim sender.
Why Yamaha 2CMH Speedometer or Comb. Speedometer & Fuel mgt gauge shows incorrect fuel level?
If the speedometer or combination speedometer & fuel management gauge shows an incorrect fuel level, the fuel sensor selection is likely wrong. Set up the fuel sensor to the correct resistance.
What to do if Yamaha 2CMH 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 causes Yamaha 2CMH 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.
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.
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.
What to do if the Yamaha 2CMH 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, if necessary, replace the gauge itself.
