  1. Fix Battery Cables

If you’re lucky, then the issue is related to the battery cables. Then you won’t have to spend hundreds of dollars on fixing this problem.

On the other hand, you can also rely on the use of a multimeter to isolate the problem.

So, just grab yourself a multimeter and check the voltage on the connection points. Ideally, you will notice around 12.6 volts of power on the battery terminals that should jump up when the motor is running.

If the reading on the multimeter doesn’t match this description, then you need to get new cables. Some people might notice that the problem is from the wirings being loose.

If this happens then the best way to fix the issue is by tightening the connections for your cables.

People should also make sure that they observe the wires before they are replaced. The best way to identify broken or damaged wires is by looking out for small cracks or breaks on them.

If you notice these then it is best that you get them replaced with new ones to fix your problem.

When it comes to the battery being used on your Yamaha Outboard, several things should be checked on it. You can start by looking out for the wires and then deal with them accordingly to fix the problem.

  1. Battery Not Working Properly

If the problem is not from the cables on your battery, then several other factors can play a huge role.

You should start by checking if there is dust gathered on the terminals of your battery. If there is, then make sure that you clean all of it properly.

The main reason it is necessary that you remove the clogs is that the dust can prevent current from passing through.

This makes it harder for the battery to function properly and it is recommended that you keep it clean. If you have not been doing this, then this might be the root of your issue.

When removing the dust and clogs from your battery, people might sometimes notice that there is some corrosion on the terminals.

This also prevents the battery from working properly which is why you might notice that it is not getting charged.

While some users can remove the corrosion by rubbing it off, you might notice that it is stuck. This only happens if you have left the battery as it is for a long time.

The best way to fix the problem is by pouring warm water on the terminals. You can also use a solution of water and vinegar.

This allows the corrosion to soften so that you can remove it much more easily. This is a great way of ensuring that all the corrosion is removed, and it also helps the battery in charging quickly.

People should remember to leave their battery for some time as it will require recharging.

If you notice that the battery dies quickly after charging, then it indicates that its life has started reducing. This is normal with older batteries as they continue to lose their charge over time.

cleaning products

The only thing that you can do in these cases is to replace the battery with a new one.

When purchasing a new battery, make sure that you select the brand carefully. There are tons of options that you can choose between but make sure that you choose a company that has reliable products.

This will help people in getting a battery that lasts them a long time without any issues.

  1. Defective Coil On The Device

If you’re sure that there are no issues with the battery cables, then you’re likely dealing with a defective lighting coil. To verify this suspicion, you should connect the multimeter to the motor terminal and check the voltage output.

If the output on the terminals is absent, then you will have to replace the lighting coil in the unit.

Issues with the regulator in the motor can also lead to the loss of voltage on the motor terminals. So, you will have to thoroughly inspect the lightning coil and regulator in your unit to get ahead of this issue.

All in all, you should be able to fix the issue after you replace the lighting coil. Make sure that you buy this carefully as the product should be compatible with your Yamaha Outboard.

The best way to ensure this is by looking for recommendations online.

If you notice that your problem is still present, then it is best that you move on to the next step. This should help you in ensuring that the problem is taken care of as soon as possible.

  1. Call an Expert to Help You Out

So, make sure to reach out to Yamaha customer support or contact your dealer regarding this issue. That way, you won’t have to waste any time troubleshooting steps that don’t match the problem.

All in all, you will be dealing with battery cable issues or lighting coil issues when your Yamaha outboard is not charging the battery.
