Is the generator adjusted internally?
If yes, connect the battery "-" to ground, "+" to the D+ terminal, and use a wrench to see if there is a magnetic field in the rotor? If not, replace it with a new regulator and try again. If it still doesn't work, disassemble the generator and use a multimeter to check the excitation coil. If it is damaged, replace it!
If the regulator is online, check to see if the regulator light is on, and use a test light to check if the “+” is lit? "—"Is it okay to take the train? Is there an output for 'F'?
Due to different car models, the model and working principle of the regulator are different. The above is to set the “+”! Make sure you understand how it works before testing!
The regulators on the line can be connected in series, that is, to set "+", directly connect "+" and "F" with wires, and to adjust "-", directly use wires to connect "-" and "F" in series”
You will know if there is any problem with the regulator!
National V truck generator is broken and can be repaired The normal generator voltage of a car generator is between 13.5 and 14.5 V. If the voltage is. too high or too low, it will cause failure The normal voltage of the car battery is above 12.5 The power generated does not depend on the carburetor or the EFI The generator of a National V truck is. an important part of the vehicle circuit system Its main function is to supply energy to the vehicle and power the vehicle's electrical and electronic equipment.
