Each motorist has repeatedly faced such a problem that it is very urgent to check the ignition system of the car, namely a spark in the candles. This is very easy to do yourself, without asking for help from specialists who work in service centers.
How to do it - look at the video:

To create a tester you will need:
- a candle;
- crocodile with wiring;
- a large crocodile;
- a piezoelectric element from a lighter;
- soldering iron;
- insulating tape4
- glue gun.
The first step is to get the spark plug from the cylinder head and carefully inspect it. Be sure to pay attention to the presence of soot on it and its amount. In the event that carbon deposits are present, then it can be removed with a small piece of sandpaper, thoroughly cleaning everything. But remember that sandpaper should be taken the smallest.
What else do we pay attention to during the inspection is the gap between the two extreme electrodes. It should be 0.7 - 0.9 mm. If the gap was slightly smaller, then in this case, the side electrode should be slightly bent to the desired distance. And if it turned out to be more - bend a little.
In addition, you need to remember that you should check the candle itself, whether it produces a spark. There are several ways to check this. For example, connect four candles to each other with a wire, which is grounded on the mass of the car. After that, connect the terminals of the high voltage wires. And then scroll the engine with the starter and watch for the spark. The disadvantage of this method is that it requires two people. one will crank the engine with a starter. And the second to watch the spark.
Therefore, we offer a simpler option for checking candles.
We solder the wire from the small crocodile to the piezoelectric element, which in turn is soldered to the large crocodile. The rations are carefully insulated with electrical tape. This is necessary so that the spark does not pierce anywhere. Also places for isolation can be filled with hot glue.
After the design is assembled, you can proceed to testing. Crocodiles are attached to different ends of the candle and a piezoelectric element is pressed. You can immediately see if the candle produces a spark.
