  1. Clean Contact Points

Issues with corrosion and debris on the contact point can lead to problems with your fuel gauge. If you don’t give much attention to the maintenance of your unit, then you will likely run into corrosion issues with your unit.

Luckily, if the situation is not that difficult, you can fix this problem by cleaning the contact points.

All you have to do is create a diluted solution of vinegar and use a damp cloth to wipe away the dust and debris from the connection point.

After that, use a clean cloth to remove the mixture residue from your unit and then connect the wires with the sender again.

Hopefully, everything will start working perfectly once the connection points are in their proper place.

Some users might ask why using a diluted solution of vinegar is important. When it comes to this, you should note that you can also fix the issue by simply using a clean cloth.


However, if the corrosion is stuck then this will be almost impossible to remove like this.

Using a solution of diluted vinegar or cleaner should help people in softening the layers of corrosion. Once done, you can then easily remove the corrosion while ensuring that the problem is fixed.

Remember to repeat the process frequently as the corrosion can come back.

This usually blocks off the connection and prevents current from passing through the wires which is why it is essential that you keep it off the device.

As long as you keep this up, the same problem should not appear again, and you can continue using the fuel gauge without any problems.

  1. Replace Broken Wires

The wires connecting your sender with the gauge can also be the source of problems with your fuel gauge. Kinks or bends in the wiring can easily disrupt the flow of power.

So, you need to inspect the wiring cluster to ensure that the wires connecting your sender to the gauge are in perfect condition.

Otherwise, the fuel gauge won’t be able to provide you with accurate information. You can also try to jerk the wires. Ask someone to keep an eye on the gauge to see whether or not that fixes your issue.

If the gauge responds to the jerks in the wiring, then you can easily isolate the problem to broken wires.

All you have to do at this stage is replace the broken wires, and the gauge will start working perfectly. If you are having trouble trying to find the broken cables, then look out for small cracks or breaks.

These usually indicate that the wire has been damaged and should be replaced with a new one.


As mentioned above, the main reason behind damage to wires is improper routing. This is why it is also essential that you prevent this from happening in the future. People should note that they can also test the wires using a voltmeter.

These devices are widely available and help when troubleshooting.

The voltmeter should provide you with the exact ratings of voltage going through the cables. This can then be compared with the standard current to isolate the damaged wires.

Once done, the only thing that you will have to do is get the cables replaced with new ones.

  1. Replace Sender

If the issue is not fixed after going through the troubleshooting steps mentioned above, then you will need to replace the sender connected to the fuel tank.

There is a possibility that your sender is defective. You need to install a new one to get around the sender problem.

With that said, it is also possible that something inside the tank is not allowing the sender to move freely in the unit. So, make sure also to inspect the tank and replace the sender after verifying its integrity with a multimeter.

If you get no response while using an external power source, then you will have to purchase a new sender. Depending upon your dealer, it shouldn’t be that expensive to get a replacement sender for your tank.

On top of that, installing a new sender is quite easy.

So, you don’t have to concern yourself with extensive installation procedures.

  1. Customer Support Team

The solutions mentioned above are most of the steps required to fix problems like these.


If you notice that you are still running into issues with the fuel gauge or if the solution did not work, then contacting the support team for Yamaha is your best option.

When it comes to this, it is important that you provide the team with detailed information regarding the problem. This allows them to isolate the issue so that it can be fixed easily.

You might get some questions asked, so make sure that all of these are answered with care.

This ensures that your problem can be found. In most cases, the team provides people with simple troubleshooting steps that can be used to fix the issue.

However, if even these do not work then your only option left will be to get the fuel gauge repaired.
