Features:
| 1. Component Type: The pulser coil is an electromagnetic sensor that helps control the timing of the ignition system. |
| 2. Small and Compact: The pulser coil is relatively small and is mounted near the engine's flywheel or crankshaft. |
| 3. Non-Contact Design: The coil operates without physical contact with other engine components, relying on magnetic fields to generate signals, which makes it highly reliable and durable in the long run. |
| 4. Durable Housing: It is housed in a protective casing to withstand the harsh environment of marine applications, including exposure to water, salt, and vibrations. |
Functions:
| 1. Ignition Timing Signal: The primary function of the pulser coil is to generate an electrical signal that informs the ignition control unit (like the CDI) when to fire the spark plug. It ensures the spark happens at the precise moment needed for efficient combustion. |
| 2. Magnetic Field Sensing: The pulser coil works by sensing the movement of magnets on the flywheel or crankshaft. When a magnet passes by the coil, it induces a small electrical pulse. This pulse is sent to the CDI unit or ignition system to trigger the spark. |
| 3. Engine RPM Feedback: The pulser coil also helps the ignition system monitor the engine's speed (RPM). Based on the pulses generated, the ignition system adjusts the timing as the engine speed changes, ensuring optimal performance at different RPMs. |
Maintenance Tips:
| 1. Inspect for Corrosion: Regularly inspect the pulser coil's wiring and connectors for signs of corrosion, especially due to saltwater exposure. Ensure the connections are clean and tight. |
| 2. Check for Damage: Examine the pulser coil and its protective housing for cracks, wear, or damage. Any cracks could allow water or dirt to enter the coil and affect its performance. |
| 3. Secure Mounting: Ensure the coil is securely mounted near the flywheel or crankshaft. If it becomes loose, it may not accurately sense the engine's position or movement, leading to misfiring or poor performance. |
| 4. Monitor Engine Symptoms: If the engine has trouble starting, misfires, or shows irregular spark timing, these could be symptoms of a faulty pulser coil. Early detection can prevent more serious ignition problems. |
| 5. Proper Storage: If the outboard motor is not used for extended periods, store the motor in a dry, protected environment to prevent moisture buildup around the pulser coil. |
Signs of Pulser Coil Failure:
| 1. Difficulty Starting the Engine: One of the first signs of a faulty pulser coil is difficulty starting the engine, as it may fail to send the ignition signal to the CDI unit. |
| 2. Engine Misfires or Stalling: An inconsistent or weak signal from a failing pulser coil can cause the engine to misfire, stall, or run roughly. |
| 3. Loss of Power: A malfunctioning pulser coil can cause irregular spark timing, leading to a noticeable loss of power, particularly at higher RPMs. |
| 4. No Spark: If the pulser coil completely fails, the ignition system may stop producing a spark, preventing the engine from starting or running. |
