    How about a picture of the wiring diagram for the ignition system

    I am not sure that one exists.

    What size of battery is in it? CCA?

    Very helpful video. Do you know the maximum wattage these stators produce? I thought it was 10 amp which would be 120 watts from my very poor (not confident) estimates but if you're running 2 - 80 watt fans with no issue it must be higher then that. Thanks.

    I do not off of the top of my head. Pretty sure the stator on this engine is 20 amp 10 per leg but do not quote me on that I would have to look at the specs.

    I recently experienced an ignition switch failure.....not waterproof.... i attempted to wire in a generic switch but with no luck. I found a stock replacement online but failed to take a picture of the harness plug wire orientation. Could you possibly show a picture of how the wires insert in the harness plug? Mine has 2 yellows together, 2 yellows w/ white stripe together, a white, a green w/stripe, and a black. Just a picture as its plugged in would work....Thanks in advance and thanks for the helpful videos...

    I have a brand new mini excavator and the ignition switch locked up to where I could not turn the key so they sent me a brand new ignition switch which I put in but now it turns over but it will not start so they sent me another ignition switch which was just a nap a universal switch with a hand Ron terrible wiring diagram. It’s still turns over but there is absolutely no spark else works. I wondered if you had any insight on this.

    I have the exact same issue, replaced switch but it’s like engine has no spark. If you figure out a remedy it be great to know.

    I am sorry I have been away for a while. But I would check the black wire that goes to your ignition coil that is what shuts the engine off by killing spark.

    Do these mini’s go into free wheel down hill ?

    I have not experienced it. But I have heard of it. I haven’t had it on any major hills yet.

    So what turns the engine off electrically? The key switch or the big electrical disconnect? And why. Thanks for your time Chad.

    Sorry I did not go over that! Thanks for calling me out. The keyswitch controls the engine kill. I will make a video on that when the weather gets above 0 degrees 😂

    I would also like more detail on the key switch. Mine has issues and I’d like to replace it but can’t figure out which wire is which.

    My ignition switch failed, so I got a Kubota switch. I IDed three of the terminals with an ohmmeter and got it to crank, start, and run. But, the engine does not stop when switched to the off position. I ended up pulling the spark plug lead. How it it designed to stop running?
