How to diagnose and replace ignition coil with no spark on your mower.

  • Metal in Motion - I wanted to show you guys how I diagnose an engine that has no spark to the spark plug. You need to determine if the problem is on the kill circuit which grounds the coil and turns the engine off, or is it the coil itself. Although this is on a push mower, the same method applies to riding mowers, pressure washers, go karts, generators, weedeaters, blowers, etc. They all use this same or similar design, and have a ground wire attached to the coil. When the on/off switch is turned off it grounds the wire going to the coil and the engine shuts down. KEEP YOUR FEET CLEAR OF THE MOWER BLADES WHEN TESTING!

    Josh is a very good instructor. Clear, concise, shows things up close and stays right on subject. Not a lot of hemming and hawing during the instruction. Now I know what I need to get my pressure washer sparking. 👍

    This video earned you a subscriber. Very detailed and knowledgeable troubleshooting tips. Most of the internet is filled with "cleaned the carburetor" or "change the oil". This is the first bit of advice I've seen that goes into the issues surrounding the ignition coil, ground wire and flywheel.
    Hoping this will fix the issue with my mower. I have a spark plug tester coming in tomorrow. Thanks for the video and most importantly, the knowledge you shared with us!

  • @gotdeeres

    Your method works if you have a spare coil. You can test the existing coil with an ohm meter. Connect one lead to the inside of the spark plug boot making sure you contact the metal inside. Connect the other probe to the engine block. The resistance should be around 3-4 K ohms. THis test can be done without removing the coil.

    • @justtinkering6713
      @justtinkering6713 9 месяцев назад

      Ohmmeter test doesn't work on my coil. I have two cylinder and one side works the other side doesn't, so I assume one coil is good. They both fail the ohmmeter test, even the good one. Swapped polarity, same thing.

    Thx , new subscriber, I am fixing the exact mower right now. I’ve had it running twice before . Not sure if her kids sabotage her mower and say it doesn’t work so they don’t have to cut the grass . We are going to follow your lead on this and tell her to never let any of her kids touch it ever again. The woodruff key was broken off this time . W t heck. He must drive it down the concrete stairs hahaha

    The only thing you didn't mention is if like you are located near salty air, a build up of rust can form on both the magnets and the coil contact face.

    Before installing a new coil, always check the gap first. I just had one where the coil had vibrated and was touching the flywheel. Re-gaped and was fine.

    Nice video. I went through all of the steps and still had no spark. Finally found the problem. The cable from the starter cable was too long. It wasn't disengaging the kill switch where the grounding cable connects to. Once I shortened the cable (search on "How to Adjust Lawnmower Cable" on RUclips), the lawnmower started on first pull.
