I have a Uncle that grew up in rural Louisianna and he told me a story about a trick they played on one of the local Bullies that if he was to Urinate on the Spark plug of a running lawn mower it would shut the engine off he said that kid rolled around for a half an hour grabbing his Junk and yelling how bad it hurt the others thought it was hysterical

@TruckTaxiMoveIt 4 года назад

In order for this video to be better appreciated you needed to have problem spark plugs: problems that you can show either a damaged spark plug, or a weak spark plug, compared to a good spark plug,

@blackkeymaestro 2 года назад

Spark plugs either work or don't work. No such thing as "weak" plugs. You either test whether they are working with this tester, or you do a visual check and see if the ends are corroded or rusted. If any of these are true, time to replace. End of story.

@lizardking8388 Год назад

@@blackkeymaestro You are wrong. Most spark plugs are resistive. They make them resistive to limit the electrical noise that gets radiated causing interference with the radio and other circuits. They will have a resistance of 5K or less measured through the center electrode. When this resistance breaks down over time and becomes more than 5K, the spark produced becomes weaker as there is less current through the spark. If a spark plug is suspected of being weak, you should remove it, clean the electrode and do a resistance check with a multimeter. If resistance is more than 5K, the plug should be replaced. If the plug is of the non-resistive type, this is not an issue as they will last much longer. Incidentally, they also make resistive and non-resistive wires which suffer the same faults and can be tested with a multimeter as well. You should use either resistive plugs or resistive wires; never both resistive or non-resistive. I prefer to use resistive plugs with non-resistive wires as the wires will have a longer longevity.

@barryf3395 11 месяцев назад

A plug that fires outside the engine is not a reliable working test. Inside the cylinder it has to be able to withstand immense pressures, varying temperatures of heat produced by the engine, burn off oil and other contaminants to function correctly. A plug that gives spark not subjected to any resistance may fail under engine working conditions.

This is a good test I believe for a no-start car to see if there’s power going to cylinders as one of the diagnostic steps .

@BeastmodeBeats 4 года назад

This test allows you to address both the ignition coil and the spark plugs. So if your coil pack needs to be replaced you’ll know based on no light from the test light. Power goes from the battery, to the ECM, to the Distributor Cap, to the spark plugs which distributes power to different responsibilities of power: compression, ignition coil and ignition relay power, airflow used to pump fuel into the throttle body to send a required amount of fuel to the engine, or fuel pump pressure & power. If too much fuel is sent to the engine your check engine light will come on. It’s referred to as fuel trim and it’s the reason a lot of cars have a check engine light because improperly distributed voltage is distributed to the fuel pump which means too much fuel is pumped into the throttle body.

@TechnoTinker 2 года назад

@@hernani1271 Sure. A bad wire or coil could fail to deliver good spark, but this sometimes depends on other factors. Some wires might perform OK under mild stress but fail at higher RPMs. If one cylinder is testing bad, you can swap the wire with a known good wire and see if the problems follows the wire or the plug. You can also swap identical coil packs to rule those out. Don't try anything you don't understand, and don't take to much advice from a random non-mechanic (me) commenting on RU-vid.

So, all 4 are working. You technically repeat the same thing 4 times for no reason. What a waste of time!!

If he has a misfire he is ruling out misfire due to electrical problem leading up to the spark plug

@@0100000101001100 After the first start up, it's evident that he doesn't have a mis-fire as the engine is running smoothly. Checking whether all the plugs are firing on a smoothly running engine is futile.

This is the worst tool I have ever used. I don't understand how you can get the rubber boot to slide, mine won't slide and I can't get the darn thing to clip. The male end keep trying to eject itself from the spark coils and after wasting about an hours trying to get it to work I lost a coil spring wich I'm not sure if I can buy on itself . So now I can't start my car and have to find a coil spring . Worst tool ever created. This incident is a proof that it's nice when everything goes well like in this video but that's probably not how it's gonna go in real life if you don't know what your doing. Hate this tool, don't buy it.
