Ignition Coil Power and Trigger coil

Power to determine the ignition coil in many ways, can block the direct power with a multimeter to measure to see whether the coil short-circuit or open circuit phenomenon. Can also be sent directly measure the voltage, this method is usually more direct. Namely: the multimeter transferred to AC voltage 20V block, a table document connected to the ignition coil output power, the other on the table document connected to the engine, step-start lever hard to see the changes in meter pointer. If the pointer will change as the engine speed changes, then the coil is good, and vice versa, then it is bad. In the case of no meter, you can find a small light bulb (or a small test light) to be tested. If you find a small light bulb with the engine speed will change, then good, otherwise the description is bad. As an alternative, you can use it the electricity, the rectifier, the charging of a capacitor, and then let the capacitor of  Street Bike to ground (engine) to discharge, in order to determine its quality. If you will discharge on the note is good, otherwise it is bad. As mentioned above, or, with a small speaker can also measure its quality.

Failure in the ignition system under the premise of the trigger coil to determine whether there is a problem that can be used to determine indirect exclusion is good or bad. Because CDI electronic ignition, the trigger level voltage and current required is very small. The trigger coil turns less. Thus, the ordinary magnetic multimeter is not easy to measure, but we can use the high sensitivity of the digital multimeter or tester, measure the relevant data and then compared with the theoretical value to determine its quality. In addition, you can find a battery to replace the coil in the ignition system is triggered in the role. To do is: the battery's negative terminal connected to the engine or the ground line, first remove the spark plug, spark plug cap to plug in where, and let the spark plug and engine block of  ATV Quad to maintain 4 ~ 5mm, rotating magnetic motor, make it in the ignition capacitor to charge, then the thread connecting the trigger coil and battery positive contact with, if there is spark, then the other parts are good, which shows the trigger coil problem.

Through the above description can be seen, only the  Motorcycle Engine ignition system failure. When confronted with the ignition system failure, should face up to difficulties, study problems, identify the law. However, in testing the ignition system, ignition system can not only consider, because the whole electrical system is interrelated and should be combined with practical, to find out the reasons for this failure to completely resolve the problem. Meanwhile, the meter can also be seen in the repair of the great role of the circuit, therefore, imperative that we equipped with a multimeter. Also, I like to like to go long distances of the riders or a small suggestion, when you are ready to embark on long-distance trip before you is necessary to prepare a set of "external ignition system."
