12.2.2.1. Check of the coil of ignition
THE GENERAL DATA

Elements of electronic system of ignition

1 – the gauge of frequency of rotation cranked
Shaft;
2 – the gauge of a corner of an advancing of ignition;
3 – the detonation gauge;
4 – the ignition distributor;
5 – a thermoswitch;
6 – the idling stabilizer;
7 – the switch of a mode of idling;
8 – the switch of full opening
Throttle заслонки;

9 – the gauge of temperature of air;
10 – the management block;
11 – a vacuum tube;
12 – the ignition coil;
13 – перепускной the valve;
14 – connecting колодка;
15 – the gauge of position of a pedal of a brake (for cars with automatic transmission);
16 – a combination of devices

Check of resistance of a secondary winding of the coil of ignition of the first type

1 – the ignition coil;

2 – the plug 1;

3 – the high-voltage plug;

4 – the plug 15

Suspension bracket connecting колодок on an arm

1 – колодка the gauge of a corner of an advancing of ignition; black colour;

2 – колодка the gauge of frequency of rotation of a cranked shaft; grey colour;

3 – колодка the detonation gauge; red colour;

4 – the plug 4

The coil of ignition established on the car, can be two types.

PERFORMANCE ORDER
1. To disconnect high-voltage and low-voltage wires from the ignition coil.
2. To connect an ohmmeter and to measure resistance of a secondary winding. It should be for the coil of first type 6,8 a clod, for the coil of the second type – 7,7 clod.
3. To connect an ohmmeter to plugs 2 and 4 or 2 and 3 and to measure resistance of a primary winding. It should be 0,5–1,5 Ohm for both types of coils.
4. If resistance of secondary and primary windings differs from specified, it is necessary to replace the coil.
