Examination
Remove the protective cap and disconnect the wires from the ignition coil.
Figure 7.3. Using an ohmmeter to measure the resistance of the primary winding of the ignition coil
To measure the resistance of the primary winding of the ignition coil, connect the ohmmeter according to the diagram shown in the figure 7.3.
If the ignition coil is working properly, there should be no break in the circuit.
Figure 7.4. Using an ohmmeter to measure the resistance of the secondary winding of the ignition coil
The original article is on: MAZBOOK.ru
To measure the resistance of the secondary winding of the ignition coil, connect the ohmmeter in accordance with the diagram shown in the figure 7.4, and compare the obtained value with the required one.
Figure 7.5. Using an ohmmeter to measure the insulation resistance of the ignition coil
Using an ohmmeter, measure the resistance between the primary winding terminal and the ignition coil housing in accordance with the diagram shown in the figure 7.5.
If the result of one of these tests is unsatisfactory, replace the ignition coil.
Removal and installation
Disconnect the cable from the negative battery terminal.
Remove the rubber protective cap and disconnect the wires from the ignition coil, after marking their location.
Loosen the bolts, remove the bracket and remove the coil from the clamp on the radiator.
Place the coil in place and secure with bolts.
Connect the wires and securely place the rubber boot.
