Suzuki Outboard Won’t Start
Suzuki Outboard Won't Start means that the engine of the Suzuki Outboard boat is not functioning properly and is unable to start. This could mean that the engine is not turning over or attempting to start, or it could mean that the engine is turning over but is not activating and running. There are a variety of potential issues that could cause the Suzuki Outboard to not start, including problems with the fuel system, ignition system, or other components of the engine. It is important to diagnose and fix these issues in order to get the Suzuki Outboard running again.
If your outboard will not start, the Suzuki factory service manual recommends following certain procedures.
Note: Before troubleshooting the electric starter system, ensure that the battery is fully charged, all cables and wires are securely connected, and the shift is in the "NEUTRAL" position.
Does the engine turn over?
The first step in troubleshooting a Suzuki outboard that won't start is to determine whether the engine is turning over with continued cranking. If the engine is turning over, the next step is to check whether the flywheel is rotating. If the flywheel is not rotating or is rotating slowly, there are a few potential causes that should be considered.
First, it is important to check the charging condition of the battery. If the battery is not charged or is not being charged properly, this could be causing the engine to turn over slowly or not at all. Additionally, it is important to inspect the battery terminals for any loose connections or corrosion, as these issues can also prevent the engine from starting.
Does the starter motor rotate?
If the engine does not turn over despite continued cranking, first check if the starter motor is rotating. If it is, inspect the pinion and overrunning clutch as well as the starter magnetic switch. If the starter motor is not rotating, check the charging condition of the battery and ensure that the battery terminals are securely connected and free of corrosion. Also, check the main (60A) and sub (30A) fuses. If the battery, fuses, and terminal connections are all in good condition, listen for a "click" sound when turning the ignition switch to "START." This indicates that the starter relay is functioning properly. If there is no "click" sound, remove the starter motor from the engine and test it under no-load conditions by connecting the battery's positive terminal to the starter motor's "M" terminal and the negative terminal to the starter motor's body. If the starter checks out fine, it is likely that the magnetic switch or connections are faulty and need to be replaced.
No starter relay “click” sound
If you do not hear a "click" sound when turning the ignition switch to "Start," there are a few potential issues to check. First, make sure the neutral switch is functioning properly. This switch is responsible for detecting if the transmission is in neutral before allowing the starter to engage. If it is not functioning properly, it could prevent the starter from activating.
Next, you should check the function of the ignition switch itself. If it is not functioning properly, it could prevent the starter relay from activating. Additionally, you should inspect the starter relay and the wiring system and connections between the starter relay and ignition switch. Any issues with these components could also prevent the starter from activating. By checking all of these potential issues, you can troubleshoot and resolve the issue of no starter relay “click” sound.
Starter relay makes a click sound
If you hear a click sound when attempting to start your vehicle and the starter motor turns under no-load conditions, but the magnetic switch and connections are functioning properly, it is possible that there is an issue with the starter brush or brush holder. In addition, it is worth checking the armature coil. If any of these components are faulty, it can cause issues with the starter motor. Make sure to thoroughly inspect and potentially replace these parts to ensure the smooth functioning of the starter system.
Overall, if the starter motor is not rotating and causing the engine to not turn over, it is important to first check the charging condition of the battery and the fuses, as well as the terminal connections. If these are all in good condition, it may be an issue with the starter relay or the ignition switch. If the starter relay makes a click sound, it is worth checking the starter brush, brush holder, and armature coil for potential issues. By thoroughly inspecting and potentially replacing these components, you can effectively troubleshoot and fix any issues with the starter system and get your Suzuki outboard up and running again.
