After changing the generator, battery and voltage regulator, can the forklift still be charged, and the charging indicator light is always on? How to solve it?

90? 495? 4 100? But these generators are almost the same. Open the key and check whether there is electricity on generator F? If there is no electricity, check whether the red line on the generator regulator has electricity. If there is electricity, the line will not work. If there is no electricity on the regulator, check the safety and wiring. My multimeter must be above 13V, and the ammeter is obvious, so I won't say much. Another reason is that power is generated but the indicator light is on. This situation is generally a short circuit between the N terminal on the generator and the regulator, and then the iron is struck between the instrument indicator and the regulator.

According to the working principle, alternator voltage regulator can be divided into:

(1) contact voltage regulator

Contact voltage regulator was applied earlier. This regulator has low contact vibration frequency, large mechanical inertia and electromagnetic inertia, low voltage regulation accuracy, easy contact spark, large radio interference, poor reliability and short service life, and has been eliminated.

(2) transistor regulator

With the development of semiconductor technology, transistor regulators are adopted. Its advantages are high switching frequency of triode, no spark, high adjustment precision, light weight, small volume, long service life, high reliability and little radio interference. Now it is widely used in Dongfeng, Jiefang and many middle and low-grade cars. (3) integrated circuit regulator

In addition to the advantages of transistor regulator, integrated circuit regulator also has the characteristics of ultra-miniature, which is installed in the generator (also known as built-in regulator), reducing external wiring and improving cooling effect. Now it is widely used on Santana. Audi and other car models.

(4) computer control regulator

After the electric load detector measures the total load of the system, it sends a signal to the generator computer, and then the engine computer controls the generator voltage regulator to turn on and off the magnetic field circuit in time, which can reliably ensure the normal operation of the electrical system, fully charge the battery, reduce the engine load and improve the fuel economy. Such as Shanghai Buick, Guangzhou Honda and other automobile generators have adopted this regulator.
