If an Onan Emerald Plus BGE Series generator has no spark after changing the spark plugs and ignition coil, possible causes include:
1. Faulty Ignition Coil Installation – Ensure the new coil is properly connected and grounded. A loose or improperly wired coil can prevent spark.
2. Defective Ignition Coil – The new coil may be faulty. Test it with a multimeter to check for proper resistance.
3. Bad Ignition Module – If the ignition control module (if present) is defective, it may not send the signal needed to fire the spark plugs.
4. Faulty Points and Condenser (Older Models) – If the engine uses breaker points, check for proper gap and cleanliness. A worn or improperly adjusted set of points can prevent spark.
5. Damaged Spark Plug Wires – Inspect the wires for cracks, burns, or loose connections that could prevent proper spark transmission.
6. Faulty Kill Switch or Safety Switches – Some generators have safety switches that ground the ignition system to stop the engine. Check for a stuck or faulty switch.
7. Bad Ignition Timing or Flywheel Key – A sheared flywheel key can throw off ignition timing and prevent spark.
8. Weak or Dead Battery – If the generator relies on battery power for ignition, ensure the battery is fully charged and providing proper voltage.
9. Faulty Voltage Regulator or Charging Circuit – If the voltage regulator is failing, it may not supply the necessary power to the ignition system.
10. Disconnected or Corroded Wiring – Check all wiring connections for corrosion, breaks, or loose connections, especially in the ignition circuit.
Testing components with a multimeter and systematically checking each part of the ignition system can help identify the exact cause.
