4. Setup and Installation
Follow these steps carefully to install the ignition coil module. Refer to your pressure washer's original service manual for specific engine diagrams if needed.
- Preparation: Ensure the pressure washer engine is off and cool. Disconnect the spark plug wire from the spark plug.
- Locate Old Coil: Identify the existing ignition coil, typically mounted near the flywheel. It will have a wire leading to the spark plug.
- Disconnect Wiring: Carefully disconnect any low-voltage wires attached to the old ignition coil. Note their positions for reinstallation.
- Remove Old Coil: Unscrew the mounting bolts holding the old ignition coil in place. Remove the old coil.
- Install New Coil: Position the new 1UQ Ignition Coil Module CDI in the same location. Ensure the mounting holes align.
- Set Air Gap: This is a critical step. Insert a non-magnetic feeler gauge (typically 0.010-0.014 inches or 0.25-0.35 mm, consult your engine manual for exact specification) between the ignition coil's laminations and the flywheel magnets. While holding the feeler gauge in place, tighten the mounting bolts securely. Once tightened, remove the feeler gauge.
- Connect Wiring: Reconnect the low-voltage wires to the new ignition coil module.
- Connect Spark Plug Boot: Firmly attach the spark plug boot from the new coil to the spark plug.
- Test: Attempt to start the pressure washer to verify proper installation and operation.

5. Operating
Once the 1UQ Ignition Coil Module CDI is correctly installed, the pressure washer should operate as intended. The ignition coil is an internal component that facilitates engine starting and running by providing the necessary spark. No specific operational steps are required for the coil itself beyond ensuring proper installation.
- Ensure all other pressure washer components are in good working order.
- Follow the starting procedures outlined in your Generac pressure washer's owner's manual.
- If the engine does not start or runs poorly after installation, refer to the troubleshooting section.
6. Maintenance
The 1UQ Ignition Coil Module CDI is generally a low-maintenance component. Regular inspection can help ensure its longevity and proper function.
- Visual Inspection: Periodically check the coil for any signs of physical damage, corrosion, or loose connections.
- Wiring: Ensure all wires connected to the coil are secure and free from fraying or damage.
- Spark Plug Boot: Inspect the spark plug boot for cracks or deterioration, which can lead to spark loss. Replace if damaged.
- Cleanliness: Keep the area around the ignition coil clean and free of debris, oil, or excessive moisture.
7. Troubleshooting
If your pressure washer experiences issues after installing the new ignition coil, consider the following common problems and solutions:
- Engine Does Not Start:
- Check spark plug connection.
- Verify the air gap between the coil and flywheel is correctly set.
- Ensure all low-voltage wires are securely connected.
- Test the spark plug for spark (use a spark tester or ground the plug against the engine block while cranking, ensuring safety).
- Engine Misfires or Runs Roughly:
- Inspect the spark plug for fouling or damage; replace if necessary.
- Check for loose connections at the coil or spark plug boot.
- Ensure the air gap is correct.
- No Spark:
- Confirm the kill switch is in the 'RUN' position.
- Check for continuity in the low-voltage wiring to the coil.
- Re-verify the air gap.
If issues persist after troubleshooting, professional assistance may be required.
