Santana electronic ignition system inspection steps:
Step 1, check the low-voltage circuit is faulty. The specific method is: in the ignition switch is connected, with a multimeter DC 25V file measurement ignition coil "+" then the column voltage and ignition electronic components on the 4th foot voltage, the normal value of 12V; then pull the distributor on the signal wiring harness, With a multimeter positive and negative table rods are connected to its two ends of the two joints, where the voltage normal value of 10.5V; and then measure the ignition electronic components 5 feet and 2 feet between the voltage, the normal value of 10.5V, This voltage value indicates that the ignition electronics may be defective.
Step 2, check the ignition coil and the central high voltage line is normal. The specific method is: first with a multimeter 10Ω file measurement ignition coil primary winding resistance, the normal value of 0.6-0.7Ω; then use the multimeter 10kΩ file measurement ignition coil secondary winding resistance, the normal value of 2.5-3.5kΩ; and then measure the central High voltage line resistance, the normal value of 0-2.8kΩ. If the above normal resistance value, then the test piece may be inside the fault, pay attention to repair as appropriate.
Step 3, if the above after the measurement are normal, indicating that the device inside and the power supply line is normal, you can then intact and then check the ignition electronic components are normal. At this point, the first turn off the ignition switch, with a multimeter (dial to DC 25V file) is the name of the rod connected to the ignition coil "+" then column, negative stick rod ignition coil "-" then column, and then unplug the signal wiring harness , Then turn on the ignition switch, then pay close attention to the multimeter pointer changes. Normally, the multimeter pointer first indicates a voltage of about 10.5V and then quickly drops to zero. Can also be in the ignition switch is connected, unplug the signal on the electrical wiring harness, in the middle of the connection with a wire, the wire quickly after the release of the cable immediately to the ignition electronic components of a simulated ignition signal, At this time, the multimeter pointer should have the same reaction as described above. If the above reaction, that ignition electronic components without failure. At this time if the car still can not start, then the fault in the ignition signal generator. Ignition signal generator and ignition electronic components can only be replaced when there is no need to repair.
Check the ignition electronic components and ignition signal generator, you can also do not use multimeter measurement, the use of the central high-voltage line plugged into a spark plug after the fire test method. If you turn on the ignition switch instantly can see the flashover or ignition switch connected to the case of the signal line quickly ground and immediately release when you can see the flashover, indicating that the ignition of electronic components and ignition signal generator are normal, Otherwise it is the ignition electronic components or ignition signal generator is faulty.
