Location of high voltage wires on the engine
Incorrect installation and positioning of the high voltage wires on the engine can cause sparks to jump from wire to wire or to «mass», which, in turn, can lead to misfiring and a decrease in engine speed when the vehicle is driven at high speed.
Therefore, install the high voltage wires properly as shown in the illustrations.
Examination
1. Clean and check the integrity of the insulation of high voltage wires. Check the inner surfaces of the contacts of high voltage wires for corrosion or deposits.
2. Using an ohmmeter, measure the resistance of the high-voltage wires.
Note. The resistance of the high voltage wire must not exceed 10,000 ohms, otherwise replace the wire.
