Yamaha 15HP Ignition & Electrical Parts
A reliable ignition system is essential for easy starting, smooth acceleration and stable engine operation.
The Yamaha 15HP ignition system uses several electrical components to generate and control the spark required for combustion.
We supply a range of Yamaha 15HP ignition and electrical spare parts for maintenance and engine repair.
Main Ignition Parts
Common components include:
- CDI Unit
- Ignition Coil
- Charge Coil
- Pulser Coil
- Trigger Coil
- Spark Plug
- Spark Plug Cap
- Wiring Harness
- Stop Switch
- Starter Relay
- Starter Motor
- Electrical Connectors
CDI Unit
The CDI controls the ignition system and determines when the spark is delivered.
Possible symptoms of CDI problems include:
- No spark
- Intermittent spark
- Engine misfire
- Difficult starting
- Sudden engine shutdown
- Unstable engine speed
Because similar symptoms can also be caused by coils, wiring or spark plugs, testing is recommended before replacing the CDI.
Ignition Coil
The ignition coil converts electrical energy into the high voltage required by the spark plug.
A weak ignition coil may cause:
- Weak spark
- Misfiring
- Difficult starting
- Poor high-RPM performance
- Intermittent engine operation
Charge Coil
The charge coil supplies electrical energy to the ignition system.
When the charge coil fails, the engine may experience:
- No ignition
- Weak spark
- Difficult starting
- Intermittent shutdown
Pulser Coil / Trigger Coil
The pulser coil sends crankshaft position information to the ignition system.
Incorrect signals can affect ignition timing and engine stability.
Spark Plug
Spark plugs should be inspected regularly.
Check for:
- Carbon deposits
- Electrode wear
- Oil contamination
- Incorrect gap
- Corrosion
A worn spark plug may cause poor starting and inefficient combustion.
Common Yamaha 15HP Ignition Problems
Ignition components should be checked when the engine:
- Will not start
- Has no spark
- Misfires
- Runs unevenly
- Loses power at high RPM
- Stops suddenly
- Has intermittent ignition
