Have you ever experienced the frustration of your open-frame portable generator suddenly stalling or refusing to start? It is a common issue that many generator owners face and one possible culprit could be a faulty ignition coil.
But fear not, This step-by-step instruction will walk you through the process of replacing the ignition coil for your portable generator, Complete with detailed instructions and images to ensure a successful ignition coil replacement.
If your generator is acting up, like randomly shutting down or misfiring after running for only a short time, like 10 or 15 minutes, it is a good idea to consider the ignition coil as a possible cause. In such cases, replacing the ignition coil might help resolve the issue.
Ignition Coil Replacement for Open-Frame Generator
How to Replace Ignition Coil in Your Traditional Generator?
Step 1: Tools Need
Before you begin, make sure you have the necessary tools & parts on hand:
- T Handle socket wrench 10-millimeter, 8-millimeter both
- New ignition coil
- needle nose pliers
- Safety goggles
Step 2: Access the Ignition Coil
First things about safety. You don’t want any unexpected sparks, right? So, start by disconnecting the spark plug cap.
That’s done Now, take a look at your generator engine flywheel cooling cover. You’ll find either 4 or 5 bolts holding it on. Grab a 10-millimeter socket, remove these bolts, and if needed, use a flathead screwdriver to remove any wire clips. Once you’ve got those off, you can take off the engine shroud and the recoil housing.
Step 3: Disconnect the Wires
After accessing the ignition coil then Identify the wires connected to the ignition coil. simply follow the spark plug wire back to the ignition coil. Carefully unscrew the spark plug cap, and then follow the other set of wires leading to underneath the panel.
Disconnect the wires connector and make sure to free the wires from any tabs that are holding them in place. These may include the spark plug wire and one wire connecting the ignition switch or electrical connections.
Gently disconnect these wires, making sure to remember their positions for reconnection later.
Step 4: Remove the Old Ignition Coil
With the wires disconnected, you’re ready to remove the old ignition coil. There are two (2) bolts holding it in place. Grab your trusty 10-millimeter socket again, and use it to remove those bolts.
Loosen the spark plug wire from the insulator and thread it back through the gap in the carburetor housing. This will allow you to fully remove the old ignition coil.
Step 5: Install the New Ignition Coil
Now, it’s time to install the new ignition coil. Slip it around the flywheel, making sure it’s positioned correctly. Loosely replace the two bolts, and push the ignition coil as far away from the flywheel as you can. Then, tighten up those bolts.
Step 6: Adjust the Gap (Coil to Flywheel)
The most important setting when adjusting the ignition coil to the flywheel on a portable generator is the air gap between the ignition coil and the flywheel magnet.
The air gap is crucial because it determines the strength of the magnetic field generated by the flywheel magnet, which in turn affects the spark produced by the ignition coil. If the gap is too large, the spark may be weak or nonexistent, causing ignition problems.
If the gap is too small, it can lead to the coil and flywheel making contact, potentially damaging both components.
With everything in place, rotate the flywheel until the magnet lines up with the ignition coil. To make sure it’s spaced correctly grab a business card and cut it in half lengthwise. Use one half as a spacer between the ignition coil and the magnet.
Loosen the two bolts slightly so that the ignition coil fits snugly against the magnet then give those bolts a good, final tightening with your 10-millimeter socket.
Now, rotate the flywheel to make sure the ignition coil isn’t hitting or rubbing against any part of the flywheel or magnet.
Step 7: Reconnect the Wires
Attach the wires you disconnected from the old ignition coil to the corresponding terminals on the new coil. Reattach the spark plug cap and Double-check the connections to avoid any loose wires.
Step 8: Replace the Cover or Housing
Start by reattaching any recoil pull starter cover you removed during disassembly and carefully place them back in their original position.
Use a 10-millimeter socket again and tighten them securely, but be careful not to overtighten, as it may cause damage.
Step 9: Reconnect the Spark Plug Wire
Reattach the spark plug wire to the spark plug. This connection is crucial for proper ignition and generator operation.
Step 10: Test the Generator
By testing your generator after replacing the ignition coil, you are making sure it’s ready for action whenever you need it.
If anything seems off during testing or if you notice any quirks, consult your manual or consider reaching out to your nearby certified mechanic.
Proper testing and maintenance will keep your generator running smoothly for a long time to come. issues.
Conclusion: Ignition Coil Replacement Process
Changing the ignition coil in your traditional generator is an essential maintenance task that can enhance its performance and extend its lifespan.
By following this step-by-step guide, completely with detailed images, you can confidently replace the ignition coil and ensure your generator continues to provide reliable power for your needs.
Remember, if you’re uncertain or uncomfortable with any step, it’s always a good idea to consult a professional technician nearby area.
