Regulator just as its name implies is to adjust generator, because the car engine speed is not certain, the generator is driven by the engine, in order to make the generator of electricity stable at around 14.0 v, you need to adjust the internal magnetic field generator current size, when low speed adjusting current is big, high speed regulating current is small, this generator can output voltage.5 wire controller, one root is the power of the regulator B, controlled by the ignition switch is equivalent to monitor the size of a generator induction line, his current of high voltage regulator out small, vice versa.Take 2 root is wire E, this is the most basic.Use electrical appliances, certainly must have wire and iron wire.Root is neutral N 3, he and the generator neutral point connected to terminal, it work normally when the voltage of the generator for half of the generator voltage, role is to control the charge indicator.Root is charge indicator line 4 L, the charging light head from the ignition switch, from the meter power into, and then received this with online, it through the regulator internal iron, charging indicator light is lit;Have the neutral point after electric power control on the voltage regulator L, charging indicator light on both ends of the potential similar lights went out.5 root is the magnetic field F, it is also connected to a generator, is it make the generator has a magnetic field with line current, can generate electricity.To judge a good regulator, to 1, the generator is not electricity, no electricity magnetic field by the test lamp end, regulator F no electricity, but there is electricity, B E take iron is normal, the regulator is out of order, with the change.Method 2, generator is too big than 15.0 v or higher that in general is also regulator is out of order, with the change.
