Check the angle of the closed state of the contacts

To contact ignition systems mandatory procedure is to check the angle of the closed state of the contacts - UZSK. Domestic avtotestery measure this parameter in degrees. Imported avtotestery can measure this parameter (DWELL - measuring cycle) in%. Speaking of normal language - is a simple check of the gap between the contact breaker with avtotestera. Normal values ??of the gap in the measurement of a simple probe are as follows: 0.35 - 0.45 mm. When measuring UZSK: 50 - 60 degrees. When measuring in DWELL: 45 - 68 percent. Any other value outside these limits are faulty and need no adjustment. Use the tester in the measurement is a more progressive method, which resulted in increased speed and reliability of the results. You do not want to waste time removing the cover of the distributor, the engine spinning over the ratchet. You simply connect the two "crocodile" and crank the engine. Readings at idle speed should not vary from the readings at higher speeds for more than two digits of the measurement. The higher the number - the smaller the gap. The lower the number - the greater the gap. UZSK value is very important for the smooth operation of the ignition system. In the operation of the vehicle normal wear and tear is the contact pair, erasing the cams and the dielectric pads. As a result, reduced the gap between the contacts of the breaker, and the digital value becomes more UZSK. Maintenance Ignition distributor is recommended after 10-15 thousand miles.
