Even though Mercury and Suzuki have dominated the market with their exceptional outboard motors, brands like Johnson Outboards have recently started to establish their name in the market. Aside from the performance of the system, motors from Johnson Outboards are quite efficient. Plus, you don’t have to think about a substantial increase in your budget. With that said, even these motors can sometimes cause issues for the anglers. Recently many anglers have been struggling with the no spark in the Johnson Outboard motor. If you’re stuck in a similar situation then let’s go through a few troubleshooting steps for this particular issue.

Dealing with the Johnson Outboard Motor No Spark Issue

1. Clean Battery Connections

If there is no spark in the motor at all then you are likely dealing with battery issues. Most of the time, this problem can be fixed quite easily by cleaning the connection points. Corrosion on these battery connections is quite common. So, you will have to clean these connection points to get ahead of the spark problem. Having clean connection points will fix the sparking issues with your motor unit.

Other than that, you should also use a voltage measuring device to check the power output from the battery. If you’ve had the battery for a long time then the possibility of battery failure is quite high. You can easily check the power output by connecting a multimeter with the terminals of the battery. Once the multimeter is connected with the points, you have to check the reading on the device and match it with optimal readings.

If you are not getting the desired reading from the multimeter then you might have to buy a battery replacement. A battery replacement can be relatively expensive. But, it will help you avoid the spark issues in the motor over the long run.

2. Replace Rectifier

If you’re not getting a spark on any cylinder in your motor then there might be a problem with the rectifier. To narrow down on the issue you should remove the rectifier from the unit and try operating the motor. If that fixes the spark issue then you will need to get a new rectifier on your motor. Luckily, this replacement won’t cost you much so you should immediately inspect the integrity of the rectifier in your unit. You can make this replacement yourself if you have experience with the overall process.

Aside from the rectifier, you should also inspect the wiring cluster for possible damages. Because of varying reasons, it is probable that you’re running into the sparking issue because of a damaged wire. So, if you find any damaged wire in the system, make sure to replace it immediately. On the other hand, if you’re unable to find any issues with the wiring cluster, you can use a voltage measuring device on individual wires to check the output. That will help you isolate the problem pretty easily.

Once the faulty wires are identified, make the replacement immediately and try operating the machine again. Hopefully, this time around, you won’t have to deal with the spark issues on your Johnson Outboard motor.

3. Replace Ignition Coil & Spark Plug

Depending upon the age of your unit, it is not that rare to run into no spark issues. Most of the time, you will have to overcome this problem by replacing the spark plug or the ignition coil. These replacements are easy to get and you won’t have to hire a professional. With that said, you can remove the top assembly. This will help you check the integrity of the ignition coil and the spark plug. If both components are in bad shape, install a replacement on your unit.

This will eliminate the spark issue from your Johnson Outboard motor and you can continue the fishing trip. With that said, you have always the option of calling the company support for professional help. Depending upon the warranty status on your unit, they will help you with all the components and complete installation guidance. This way, you won’t have to worry about making the purchase on the components yourself.

So, just reach out to customer support and explain your issue to them. They will help connect you to a professional. This professional will help isolate the problem in your unit. They’ll then recommend practical solutions that you can try immediately.
