有时启动电机电磁开关触点粘连在一起,致使启动电机运转不停,虽然启动用的钥匙转回到“Ｏ”的位置,启动电机依然转动。产生这种故障的主要原因:一是使用方法错误,启动电机运转时间过长;二是冬季发动机启动之前没有预热,导致启动电机超负荷运转;三是一般启动机电磁开关工作时将 Sometimes start motor electromagnetic switch contact adhesion together, resulting in non-stop start running motor, although the key to start turning back to the “O” position, start the motor still rotate. The main reason for this failure: First, the use of methods wrong, start the motor running time is too long; Second, before the start of the winter engine does not preheat, causing the starter motor overload; Third, the general starter magnet switch will work
