Ignition system troubleshooting circuit, voltage test
Checked element | Test Method | Set value | Cause of malfunction |
Ignition wires | Disconnect the switch connector, turn on the ignition, measure the voltage between the plugs «4» And «2» switch connector, then turn off the ignition | U=~12 V | In case of deviation from the norm, breakage, damage to the wires of the ignition system |
Switch | Disconnect the ignition distributor sensor connector, turn on the ignition, measure the voltage between the terminals «1» And «15» ignition coils | U≥2 V, U=0 V after 1-2 s | In case of deviation from the norm, the switch is faulty |
Switch | Turn on the ignition and measure the voltage between the terminals «1» And «15» ignition coils, briefly shorting to ground the central wire of the ignition sensor-distributor connector | U=2 V (briefly) | In case of deviation from the norm, breakage, damage to the wires of the ignition system or the switch is faulty |
Switch, wire integrity and reliability of their connections | Measure the voltage between the outer wires of the ignition distributor sensor connector | U≥5 V | In the event of a deviation from the norm, a break, damage to the wires of the ignition system, or a switch is faulty |
Ignition distributor | Short to ground the secondary winding of the ignition coil and measure the voltage with the switch connector between the plugs not disconnected «6» And «3» from the side of the wires, turning the engine crankshaft manually | U=0-2 V | Faulty ignition distributor |
