8.5.3.4. Ignition coil

Check resistance of windings and resistance of isolation.
Resistance of primary winding at 20 °C has to make 3,07–3,5 Ohms, and a secondary winding 5400–9200 kOhm. Isolation resistance on weight has to be not less than 50 megohms.
At the coil of ignition 27.3705 used in contactless system of ignition, resistance of primary winding at 25 °C has to make (0,45±0,05) Ohms, and a secondary winding (5±0,5) kOhm.
At the dry coil of ignition 3122.3705 with the closed magnetic conductor, too applied in contactless system of ignition, resistance of primary winding at 25 °C has to make (0,388±0,039) Ohms, and a secondary winding (4,23±0,42) kOhm.
