SEQUENCE OF WORK
Pic. 9.8. An arrangement of fixing brackets of fixing of an electric socket of the block of ignition
1. Squeeze the mounting brackets and disconnect the electrical connector from the ignition unit (pic. 9.8).
2. Check up, whether tips of high-voltage wires and universal electric sockets are reliably connected to the ignition coil and the control block. Insecurely fastened high-voltage wires due to overheating can rise slightly in the contact bushings, which will lead to misfiring. Loose high voltage wires on spark plugs can cause electrical leakage and uncontrolled fires.
3. Check the ignition coil housing for cracks or spark marks.
4. The wire contacts must not be oxidized and must be securely connected to the spark plug tips.
5. High-voltage wires connecting the ignition unit to the spark plugs usually do not cause problems for the normal operation of the ignition system. However, the high values of the secondary voltage of the electronic ignition system place high demands on the quality of the wire insulation, since the insulation must protect the wire from moisture and salt solutions. Check the high voltage wires, their insulation should not be frayed or damaged. Damaged high voltage wires must be replaced immediately. To detect non-obvious damage, bend the wire in a suspicious place.
6. If a spark jumps on «mass» through the insulation of the wire, a characteristic sound of an electric discharge will be heard in the engine compartment.
7. At night, these spark discharges are very clearly visible. The reason for this may be a coating of salt on the wire insulation or wear of the insulation.
