实例一故障现象:一辆重庆·雅马哈CY80型摩托车,停车后再启动,无法启动。故障分析排除:开始时怀疑油路堵塞、无混合气进缸,经查油路正常,再检查电路也正常,火花塞有强烈火花,但在做跳火试验时,发现火花塞不只是电极部分有电火花,其它金属部分也都产生电火花。用万用表测量火花塞两电极,有短路现象。换一只新火花塞后,一切正常。
Example A failure phenomenon: a Chongqing Yamaha CY80 motorcycle, stop and then start, can not start. Failure Analysis and Troubleshooting: The beginning of the suspected oil blockage, no mixture into the cylinder, check the oil normal, and then check the circuit is also normal, spark plugs have a strong spark, but in the flashover test, found that the spark plug is not only part of the electrode has electricity Sparks, other metal parts also have electric sparks. Measure the spark plug two electrodes with the multimeter, there is short circuit phenomenon. After changing a new spark plug, everything is normal.
