Faulty or damaged coils will have weak or no output. Receiving voltage from the CDI unit the coil will amplify voltage and shoot it through to the spark plug. Often a faulty CDI unit will see intermittent or no spark on cylinders and may only breakdown when your engine warms up.

Additionally, a faulty trigger shorting to ground will damage a power-pack so be careful if fitting a new power pack.ĭepending on your outboard brand these units will go by different names but, they will all have the same function and that is to store voltage from the stator and release it to your ignition coil when the trigger tells it to. A faulty trigger will result in no or intermittent spark and is often misdiagnosed as a fault with the power pack.

Probably the most overlooked part of the ignition system the trigger sends a signal to the CDI unit (power pack or switchbox) and tells it when to release voltage to the coil. Nestled in with the stator under the flywheel is the trigger (or timer base). Engines with no spark or intermittent spark on one bank can be caused by a faulty stator.

To send voltage to your CDI unit (power pack or switchbox) to run your engine and to send voltage to your rectifier/regulator that will charge your battery. Your stator creates voltage for two reasons. Broken or loose magnets on your flywheel will cause ignition issues so they are definitely worth checking. The flywheel also spins around the trigger (or timer base) to determine your engines firing sequence or timing. On the inside of the flywheel are magnets that spin around a stator at high speed to create AC voltage. When your starter motor is turning over it is spinning your flywheel to create voltage for your ignition system and battery charging system. If you're turning your key and the starter motor isn't cranking then you may have a faulty solenoid. The ignition switch sends a signal to the solenoid when you turn your key allowing it to open this allows voltage from your battery to pass through it to the starter motor. A faulty ignition switch can cause all sorts of problems with your ignition system and is more often than not overlooked. It also turns the engine off by shorting the CDI unit (power pack or switchbox) to ground. Every electric start outboard has an ignition switch and it will open and shut the starter solenoid. To activate your engine and crank it over you need a switch. Without the correct voltage, your outboards starter motor may not be able to crank the flywheel fast enough to activate your ignition system. Outboards require higher cold cranking amps than many other engines and therefore a dedicated marine battery with the correct cranking capacity for your outboard is a must. Your boat battery is where it all starts. The following is a list of what makes up an ignition system from start to finish. Apart from having the right tools to assist in diagnosis, a basic understanding of how a two stroke ignition system works is fundamental.

Whilst I am always happy to try and help in diagnosis, it can be very hard to do so over the phone. The most common thing I get asked over the phone to assist with is diagnosing outboard ignition problems. Troubleshooting 2 Stroke Ignition Problems
