Toyota Unser’s battery led light indicator intermitent on and off at the dash board, first not so frequent but after few days the light on/off more frequent, when the battery led light on the air-conditonal sound louder. Suspected it was the alternator giving problem and it may spoilt the battery if not fix. So I ask a mechanic friend (Ah Choy) checked on it, it caused by the alternator too dirty and oily, after serviced it work ok.(Service charger was RM30)
An alternator is an electromechanical device that converts
mechanical energy to electrical energy in the form of alternating current.Most alternators use a
rotating magnetic field with a stationary armature but occasionally, a
rotating armature is used with a stationary magnetic field; or a linear
alternator is used. Alternator mounted on an automobile engine with a serpentine belt
pulley.
Alternators are used in modern automobiles
to charge the battery and to power the electrical system when
its engine is running. Until the 1960s,
automobiles used DC dynamo
generators with commutators. They were first introduced by
the Chrysler Corporation on the Valiant in 1960, several years ahead of Ford and GM.
丰田王凤琴电池的仪表板LED指示灯间歇性开启和关闭的，第一个不那么频繁，但几天后开/关的光更频繁，当电池LED指示灯间的冷气的声音更响亮。怀疑这是交流发电机发出的问题，它可能会被宠坏的电池，如果无法修复。所以，我问一个机械的朋友（阿财）检查，它引起的发电机过脏，油腻，后服务工作正常。（服务充电器是RM30）
的发电机是一种机电设备，机械能转换为电能的交流电流的形式中。大多数交流发电机使用的旋转磁场与一个固定的电枢，但偶尔使用一个固定的磁场，旋转电枢;或使用线性发电机。交流发电机安装在汽车上的发动机与蛇形皮带轮。
在现代汽车中使用的交流发电机对电池进行充电，并电气系统的供电时，其发动机运行。直到世纪1960年代，汽车用直流电机发电机的换向器。他们首先推出的克莱斯勒公司在1960年的威力，未来几年，福特和汽车通用。
