    Thanks for the video!
    I have a Honda 1200W 71CC 2-Stroke generator, for which I have no manual and can't find one. However, the Pulsar PG-1202S generator is not only a very close match, it's almost identical.
    The Spark Plug is not getting any spark. Even though I tested the plug with an ohm meter, I decided to buy a new one, (with a resistor) just in case the old one may have a crack somewhere. Neither plug will produce a spark (grounding the plug to the engine and pulling the cord), and I've since found out how to test and discern if the problem is in the magneto/"High Voltage Set", or in the wiring.
    I'll be doing that test soon but I want to say, it's interesting to note that none of the coils you've covered in this video look like the magneto or the High Voltage Set assembly that I'm dealing with. In as many that you've covered, this fact surprises me!
    I don't think I can post a link to the Pulsar PG-1202S or to the PDF manual in this comment section but I'll try. Maybe you can take a quick look at it and tell me a way I can test that system.
    Even though the manual for the Pulsar has a section covering the different components, (a parts list, as it were), the parts are drawings and not very good drawings.
    The page 31 covers the "Ignition System Assy" and the magneto is so poorly drawn as to be hardly recognizable. The only part I can recognize and see in the engine is what Pulsar calls the "High Voltage Set" (Part #PG1202S-G-04) as drawn in page 31. They ID the "Magneto" as part #PG1202S-G-02.
    I'm trying to find that magneto section in the engine but these hand drawings don't show where it would be located and or how to get to it. I'm sure I can find and remove it but before I go through all that, I'd like to test to determine if the problem is in the wiring or the ignition first.
    Thanks again,
    Rich

    Very good video Arch just a note on the Honda coils with the screw on plastic boot which i believe you did not have in this video. This boot actually has a built in resistor so you need to unscrew the boot to check directly to the wire. On three occasions this year only the boot needed to be changed since it was measuring over 10k ohms but the coil itself was in specification. Replacing the boot was way less expensive than an entire coil.

    What is the ohm relationship between coils and spark plugs. If the measured ohm resistance range for 2 cycle mower is between 5k and 10k ohms. The spark plug selected should have a higher heat rating a 4 as opposed to a 7. What Ohm range should I look for when testing coils less than or equal to / greater than or equal to?

    • @TheNovaJohn
      @TheNovaJohn  4 месяца назад +1

      Good questions, lets separate your comment; 1st, heat range of plugs.
      The heat range selected for 2 stroke will be for a 'Hotter' plug due to the presence of oil in the mix! A Hotter running plug will help to burn off the oil and keep things running smooth longer as apposed to a 4 stroke engine where the gas has no oil in it.
      2nd, the plug ohm reading is due to the anti-noise / Radio Frequency (RF) reduction. Its used as a filter to stop any static. Most electrical things today have these restrictions from the FCC.
      This has no real bearing on the coil ohms but one could argue that for performance engines it may reduce some spark.
      Lastly, the purpose of this video is to show some "Real World" values so what can we conclude?
      Its confusing I know and I say in the beginning to check the manufacturers diagnostic sheets on coil specs and tolerance.
      In some cases that isn't available so in my view I would bias myself to slightly lower ohm readings!
      If you noticed, in some cases the coils get these very low ohm readings that are close to being shorted vs other where the ohms is so high as to be a non connection!
      In summery, less than or equal to.
      hope that helps, great question!

    Thankyou for the well explained on how to test ignition coil. But I'm confused about the reading of 10 ohms when I tested one of the coil. Is it right or wrong?

    • @TheNovaJohn
      @TheNovaJohn  Год назад

      It depends, what coil? Where are you measuring?
      Typically if you measure from the metal body to the control, 10 ohms may be fine
      I mentioned that you can go to the engine manufacturer (search youtube) model/engine code and find the chart..

  • @carlodonnell146
    @carlodonnell146 Год назад +2

    Maybe you intend cover it eventually, but it is important to know that the coil has to be installed the correct way up, as I found out; It won't fire if it is upside down, I suppose the magnetism has to travel through it in a specific direction.

    • @TheNovaJohn
      @TheNovaJohn  Год назад

      Yup,, I thought I did and may have somewhere in this video,,not sure.
      I did a video on this however. I also showed putting a new designed coil from a little briggs OHV on an old huge 17hp single slug engine with points!
      In that video I show and speak about reversing the coil, issues with rust and damage effecting the magnetic field thus causing a no spark condition!

    I enjoy watching your videos they are very well done. I recently tested the coil on my Briggs & Stratton lawnmower engine. The readings I got for the three test points were both 4.72 ohms. Is it acceptable to have both numbers be identical?

    • @TheNovaJohn
      @TheNovaJohn  2 года назад +3

      That's odd, typically no. As we can see through these tests we don't see it. For the secondary that would be too low. Something up to 6 thousand ohms would be what I would want to see.

    So when testing a briggs coil do we want more or less ohms from plug wire to ground? I always thought if it showed more ohms it was a better coil.

    • @TheNovaJohn
      @TheNovaJohn  Год назад

      Like I mentioned in the intro, if we go to the manufacturers site for the coil specs, we see a 'range' of values that are acceptable! So there is No one value.
      Now typically less Ohms or resistance, it becomes closer to a short, as in a few ohms we actually have a shorted circuit.
      More Ohms, the device becomes closer to an open circuit.
      There is a place where too much resistance means too much energy is just lost from the input.
      Now if we get closer to the max allowable resistance the coil is becoming out of spec! Below the correct range, once again closer to a short and again below the spec.
      We can see in the video how much they can vary!

    what does a heat distortion on the coil wrap tell you? My signal wire enters in that general area where the wrap has separated by a good 1/8" and now I have a signal to ground very high, 365 ohm. My Primary - secondary is normal, 2.75 kOhm.

    • @TheNovaJohn
      @TheNovaJohn  8 месяцев назад

      One of the reasons I did sooo many coils is to show how these do vary quite a bit especially over time and Heat!
      I've noticed that heat/time can make small changes that show only in a weak spark or one when intermittently give us trouble!
      Another thing I noticed and didn't mention there but in my livestreams is aftermarket coils are a gamble!
      Especially when having issues with a factory coil and then going out and buying a knockoff can really confuse us!
      Dirt on an air cooled engine can kill a coil!
      Not to mention the engine,, things get hot especially on a hot day! Imagine, its cooled by the fan but once the engine stops, basically the temp goes way up for a time and it cooks things!

    • @TheNovaJohn
      @TheNovaJohn  Год назад

      Short answer is No but the principle is the same as any briggs, its just that they have one primary control and coil and two secondary and they should match very closely in OHMs.
      Was just chatting about these engines in my lives recently.

      If one coil is bad then replace both at this point..
      While its running, pull one coil/plug wire at a time..This info might prove useful.
      Check the plugs, clean them up if they need it and re-test.
      Often a coil will run until its hot, so you may need a cold then hot plug and coil test.
      Also check the head bolts for tight and look for head gasket leaks, do a compression test cold and hot as well.

    Thru the kill wire that they are both connected to thanks tom

    • @TheNovaJohn
      @TheNovaJohn  2 года назад

      Let me clarify; you say "trigger module" that little tang is the control wire, if it is grounded to the chassis via some kind of "Kill Switch" the coil wont fire.
      If more than one coil is mounted on an engine, the point of control is a switch lets say on the console, when the switch is closed creating a path to ground, any coil no matter how many will be grounded to that point and wont fire.
      One coils control wire is unto itself. If that coil is bad lets say that control tang is open as if its not connected (burned out) it wont effect anything, conversely if that control tang is shorted to itself as in the body of the coil, it cant fire and it wont effect any other coil.
      If trigger module means something else, please clarify.

    • @TheNovaJohn
      @TheNovaJohn  2 года назад

      yes,, typically they are lower when new. As I mention in the tutorial, if you look up your engine you will find the coil specs, the manufacturer witll give a range of what they consider good. That is usually fairly wide. Keep in mind a thousand ohm difference may not be much but a mega ohm would be way too high

  • @garyr7027
    @garyr7027 Год назад +1

    Wonder how many coils get tossed when the coil itself is fine, and it was the coil wires that went toast? Not sure about the newer coils, but at one time the wires screwed on and under it was a probe the core of the wires made contact with. I've replaced wires before and actually fixed coils. The wire core is the same as in a vehicle, a fiber core, and when they go bad they go high in resistance. Plus, a bad wire can make coils run hot, forces the coil to quit, and in some cases work again once it cools down. Doing coil readings with bad wires can indeed cause many good coils get thrown away even if the wires are glued on, glueing another one in its place could get it going again. I know most people wouldn't do that, and just buy a new coil only to end up worse in some cases with cheap aftermarket parts with crappy wires... Lol. I learned a long time ago the hard way, cheap wires are not even worth the effort, as they can prematurely burn coils out in some cases... this is a fact. Coils are just transformers, and with bad wires it effects induction transfer making them run too hot. Imo, cheap wires create 90 percent of coils going bad in normal conditions.

    A lot of these plug wires are carbon core with a carbon impregnated string....start twisting the plug cap and the string breaks leaving you with a carbon track only. I've seen manufacturing defects where the string isn't even present until several mm up inside the plug cable. I'll use an NGK screw on boot after trimming back the cable and verifying the string is present. Will almost never fail at the cap again.

      As I mentioned, these are the most common coils I see and most will that are out there>
      No one single coil can fire 2 plugs. Coils are controlled by the engine timing system. Either a camshaft lobe or in these cases its a magnet that in part control of energizing these coils.
      Engines with more than one cylinder are fired at different times. This requires a separate coil.
      I have seen some very esoteric engines that will fire other plugs at events that wont produce any power. There is a name for this but I cant remember. Not something we would see in the small engine world of mowers and machines.
