Obvious signs of malfunction in the ignition system becomes a refusal when trying to start a car and improper engine operation. Determine the reason simply, if you know the principle of operation and possible problems.
1
Disconnect the high-voltage wires from the tips of the candles and install them so that the distance between the "root" of the candles and the "mass" of the engine does not exceed 2-5 mm. After start the engine starter, with active work there may be a periodic appearance of the sparks of red or blue, or they will not be at all.
2
Blue sparking indicates a high voltage admission to spark plugs. In this case, it is necessary to test the candles on a special device. Also, the inoperability of the candles can be caused due to abundant condensation on the outer parts of the insulator. If as a result of the verification it turns out that the candles are in working condition, then you need to check the ignition system.
3
Inspect the correct connection of the wires in the jacks of the distributor cover and the ignition coil, as well as the integrity and corresponding fastening of other wire of the ignition system. If you discovered the burnt or punched areas, it is necessary to carry out a comprehensive replacement of the ignition coil or the distributor cover. After check for the presence of high voltage voltage directly on the coil.
4
Disconnect the central wire from the distributor and see if the spark is, as mentioned earlier. The presence of high voltage on the central wiring indicates a malfunction of the distributor. If the high flow of charge on the wire is not observed, check the ignition coil. One part of the central wire is located 2-3 mm from the "Mass" of the engine, then disconnect the low voltage wire from the distributor and lightly, rhythmic movements touch the housing to them. When removing the wire from the housing should slip the spark. If there is no sparks - the ignition coil is faulty.
5
If manipulating wires, the high voltage on the coil did not disappear, the problem in the ignition coil or distributor. The distributor may occur in the distributor: abundant contamination or fire of the interrupter contacts, decrease the angle of the closed state of contacts or the condenser crack. The active work of the ignition coil and the capacitor is determined by their phased replacement for new serviceable spare parts. If after that the engine is normally started, it means that the cause of the breakage you are determined correctly.
If you just recently become the owner of the vehicle and so far you do not have the necessary skills, you should not climb under the hood. Contact professionals and watch their actions, feel free to ask, clarify and ask to show every detail, because such troubles can comprehend on a remote site of the track where there is no one hundred.
