一、起动继电器有内、外搭铁两种。本身搭铁的,叫内搭铁起动继电器,它装在用交流发电机的汽车上。在发电机内部搭铁的,叫外搭铁起动继电器,它装在用直流发电机的汽车上。但外搭铁继电器,可以改为内搭铁继电器,内搭铁继电器不能改为外搭铁继电器。二、电子调节器,有内外搭铁两种。各自匹配内外搭铁的发电机。若误将内搭铁的发电机配外搭铁 First, the starting relay has two kinds of inner and outer ground. Ground itself, called the ground to start the relay, which is installed in the car with an alternator. In the generator inside the ground, called the outer ground relay, it is installed in the DC generator with the car. But outside the iron relay, you can change to within the ground relay, within the ground relay can not be changed to the ground relay. Second, the electronic regulator, both inside and outside the ground. Matching both inside and outside the generator. If the mistake will be within the ground with the generator outside the ground
